We can divide both sides of this expression by either side to get one of two possible conversion factors: The first conversion factor can be used to convert from mass to moles, and the second converts from moles to mass. In the lab, however, chemists are unable to count out molecules and place them in a reaction flask. Did you find this document useful?

Taxol is a powerful anticancer drug that was originally extracted from the Pacific yew tree (Taxus brevifolia). Now that we have introduced the mole and practiced using it as a conversion factor, we ask the obvious question: why is the mole that particular number of things? The example shows the molecular ratios of the substrates and products of the reaction. 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. The study of the numerical relationships between the reactants and the products in balanced chemical reactions is called stoichiometry. That information still needs to be specified. 2 and keeping a copy in your notebook. We established that 1 mol of Al has a mass of 26. Because one mole of a substance will have a certain mass, we can use that relationship to construct conversion factors that will convert a mole amount into a mass amount, or vice versa. Recall that we can relate a molar amount to a mass amount using molar mass. 02 × 10 23 items and thus, it is used by chemists to represent a large number of atoms or molecules.

This only increases the amount of starting material needed. For some minerals, the body does not require much to keep itself operating properly.
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. 02 X 1023), the coefficients used in chemical reactions can also be thought of as molar ratios. 2. is not shown in this preview. You're Reading a Free Preview. Thus, an important three way relationship is formed: 1 mol = atomic or molecular mass in grams = 6. The simplest type of manipulation using molar mass as a conversion factor is a mole-mass conversion (or its reverse, a mass-mole conversion), as shown in Figure 6. How many grams of HCl can a 200 mg dose of Mg(OH) 2 neutralize? For the reaction in which hydrogen and oxygen combine to make water, for example, we can construct the following ratios: We can use these ratios to determine what amount of a substance, in moles, will react with or produce a given number of moles of a different substance. 011 × 10 23 C 6 H 6 molecules.
