Hemoglobin (molar mass is approximately 64, 000 g/mol) is the major component of red blood cells that transports oxygen and carbon dioxide in the body. 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.
4 Mole-Mass Conversions. In this section you will learn how to use a balanced chemical reaction to determine molar relationships between the substances. We can use the coefficients of a balanced chemical equation to relate moles of one substance in the reaction to moles of other substances (stoichiometry). This only increases the amount of starting material needed. This effectively gives us a way to count molecules in the laboratory using a common balance! We need a number that represents billions and billions of atoms.
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). 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. 1 "Water Molecules" shows that we need 2 hydrogen atoms and 1 oxygen atom to make 1 water molecule. It reacts with hydrochloric acid in the stomach according to the following reaction: Mg(OH) 2 + 2HCl → MgCl 2 + 2H 2 O.
