Calculate the mass percentage of calcium and phosphors in calcium phosphate |
|
Answer» ANSWER Molecular formula of calcium phosphate is CA 3
(PO 4
) 2
. Its MOLAR mass is 3(40)+2(31)+8(16)=310 g/mol. Percent of calcium = 310 120
×100=38.71% Percent of phosphorus = 310 62
×100=20.0% Percent of oxygen = 310 128
×100=41.29% |
