Chapter 3 - Stoichiometry - Exercises: 58

Answer

a. $465.\text{ grams $P$}$ b. $310.\text{ grams $P$}$ c. $155.\text{ grams $P$}$

Work Step by Step

a. $5.00\text{ mol}*\frac{3 \text{ mol $P$}}{1.00\text{ mol $P_3O_6$}}*\frac{30.97376\text{ grams $P$}}{1\text{ mol $P$}}=465.\text{ grams $P$}$ b. $5.00\text{ mol}*\frac{2 \text{ mol $P$}}{1.00\text{ mol $Ca_3(PO_4)_2$}}*\frac{30.97376\text{ grams $P$}}{1\text{ mol $P$}}=310.\text{ grams $P$}$ c. $5.00\text{ mol}*\frac{1 \text{ mol $P$}}{1.00\text{ mol $Na_2HPO_4$}}*\frac{30.97376\text{ grams $P$}}{1\text{ mol $P$}}=155.\text{ grams $P$}$
