Calculate the mass percent composition of lithium in Li₃PO₄. A) 26.75% B) 17.98% C) 30.72% D) 55.27% E) 20.82%

Question

Quizplus · Accepted Answer

To find the mass percent composition of lithium in Li₃PO₄, calculate the molar mass of the compound and the total mass of lithium. The molar mass of Li₃PO₄ is approximately 115.79 g/mol (Li: 6.94 g/mol, P: 30.97 g/mol, O: 16.00 g/mol). The total mass of lithium in Li₃PO₄ is 3 * 6.94 g/mol = 20.82 g/mol. The mass percent of lithium is (20.82 g/mol / 115.79 g/mol) * 100% = 17.98%.
