Question

Ca3(PO4)2 find molecular mass

Answer 1

Explanation:

Ca3( PO4)2

atomic mass of calcium ( Ca) = 40 g/mol

atomic mass of phosphorus ( P) = 31 g/mol

atomic mass of Oxygen ( O) = 16 g/mol

molecular mass of C3(PO4)2 = 3 × 40 + 2× (31+ 64) = 120 + 2 × 95 = 120 + 190

= 310 g/mol

Answer 2

ca= 40, P=31,O = 16

Mass= 3× 40 +2×31+8×16

=120+62+128=310u
