CH103: Allied Health Chemistry
Posted on 17-Apr-2021
Although this works, most of the reactions occurring around us involve much larger amounts of chemicals. Even a tiny sample of a substance will contain millions, billions, or a hundred billion billions of atoms and molecules. How do we compare amounts of substances to each other in chemical terms when it is so difficult to count to a hundred billion billion? Actually, there are ways to do this, which we will explore in this chapter. In doing so, we will increase our understanding of stoichiometry, which is the study of the numerical relationships between the reactants and the products in a balanced chemical reaction. Back to the Top 6. If we want to make 2 water molecules, we will need 4 hydrogen atoms and 2 oxygen atoms.

If we want to make 5 molecules of water, we need 10 hydrogen atoms and 5 oxygen atoms. The ratio of atoms we will need to make any number of water molecules is the same: 2 hydrogen atoms to 1 oxygen atom. Figure 6. One problem we have, however, is that it is extremely difficult, if not impossible, to organize atoms one at a time. As stated in the introduction, we deal with billions of atoms at a time. How can we keep track of so many atoms and molecules at a time? We do it by using mass rather than by counting individual atoms.

A hydrogen atom has a mass of approximately 1 u. An oxygen atom has a mass of approximately 16 u. The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately If we have 2 atoms of each element, the ratio of their masses is approximately , which reduces to —the same ratio. If we have atoms of each element, the ratio of the masses is approximately 1,, which again reduces to As long as we have equal numbers of hydrogen and oxygen atoms, the ratio of the masses will always be The same consistency is seen when ratios of the masses of other elements are compared. For example, the ratio of the masses of silicon atoms to equal numbers of hydrogen atoms is always approximately , while the ratio of the masses of calcium atoms to equal numbers of lithium atoms is approximately So we have established that the masses of atoms are constant with respect to each other, as long as we have the same number of each type of atom.

Consider a more macroscopic example. If a sample contains 40 g of Ca, this sample has the same number of atoms as there are in a sample of 7 g of Li. What we need, then, is a number that represents a convenient quantity of atoms so we can relate macroscopic quantities of substances. Clearly even 12 atoms are too few because atoms themselves are so small. We need a number that represents billions and billions of atoms. A mole is defined as 6. Just as a dozen implies 12 things, a mole abbreviated mol represents 6.

Why is it 6. Whereas one hydrogen atom has a mass of approximately 1 amu, 1 mol of H atoms has a mass of approximately 1 gram. And whereas one sodium atom has an approximate mass of 23 amu, 1 mol of Na atoms has an approximate mass of 23 grams. One mole of a substance has the same mass in grams that one atom or molecule has in atomic mass units. The numbers in the periodic table that we identified as the atomic masses of the atoms not only tell us the mass of one atom in atomic mass units, but also tell us the mass of 1 mole of atoms in grams!

This is because all atoms are made up of the same parts protons, neutrons, and electrons with the protons and neutrons having nearly identical masses. Electrons, since they are so light, are negligent in their contribution to atomic mass, even in the largest atoms. Thus, an atomic or molecular mass is indicative of how many atoms or molecules are present. This effectively gives us a way to count molecules in the laboratory using a common balance! Note that in chemical equations and calculations that mole concentrations are abbreviated as mol. Recall that, the mass of an ionic compound referred to as the formula mass or a covalent molecule referred to as the molecular mass —is simply the sum of the masses of its atoms. To calculate formula or molecular masses, it is important that you keep track of the number of atoms of each element in the molecular formula to obtain the correct molecular mass. Thus, we can the formula mass of this compound by adding together the atomic masses of sodium and chlorine, as found on the periodic table Figure 6.

The mole concept can be extended to masses of formula units and molecules as well. The mass of 1 mol of molecules or formula units in grams is numerically equivalent to the mass of one molecule or formula unit in atomic mass units. For example, a single molecule of O2 has a mass of As with atomic mass unit—based masses, to obtain the mass of 1 mol of a substance, we simply sum the masses of the individual atoms in the formula of that substance.

The mass of 1 mol of a substance is referred to as its molar mass , whether the substance is an element, an ionic compound, or a covalent compound. The major mole conversion factors are shown. The relationship of the mole quantities to gram conversion factors listed above in Figure 6. They make it possible to set up chemical reactions in a safe and efficient manner and they have tremendous impact on the economics of many industrial and manufacturing processes and the production of medicine. If you are a serious student of chemistry, I would recommend printing out table 6. It will be extremely useful in setting up a multitude of word problems and is functionally useful in the laboratory.

So why is the relationship between the mole and compound mass so important? In the microscopic world, chemical equations are set up on the scale of molecules. As we learned in Chapter 5, the coefficients in front of each compound represent the number of molecules needed for the reaction to proceed. In this combustion reaction, 2 molecules of butane C4H10 react with 13 molecules of oxygen to produce 8 molecules of carbon dioxide and 10 molecules of water. In the lab, however, chemists are unable to count out molecules and place them in a reaction flask. Molecules are way too small to be seen by the naked eye and there is no equipment available that is capable of sorting and counting molecules in this way.

Mass, on the other hand, can easily be measured using a balance. Thus, the relationship of mass to the number of molecules present becomes a very important conversion. Since the mole represents a fixed number of molecules 6. Instead of reading our equation in terms of molecules, we can read it in terms of moles. At the macroscopic level, the reaction below reads: 2 moles of butane C4H10 react with 13 moles of oxygen to produce 8 moles of carbon dioxide and 10 moles of water. The example shows the molecular ratios of the substrates and products of the reaction. In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units or, conversely, mass units into mole units.

We established that 1 mol of Al has a mass of Both can be used to solve problems. Conversions like this are possible for any substance, as long as the proper atomic mass, formula mass, or molar mass is known or can be determined and expressed in grams per mole. Note that it takes one mathematical step to convert from moles to mass or from mass to moles.
