Answer:
380.5g/mol
Explanation:
The molar mass of a compound can be obtained by adding the molar masses of the elements present in the compound.
The molar mass of Cu3(PO4)2 can be obtained as follow:
Molar Mass of Cu = 63.5g/mol
Molar Mass of P = 31g/mol
Molar Mass of O = 16g/mol
The molar mass of Cu3(PO4)2 = (63.5x3) + 2[31 + (16x4)] = 190.5 + 2[31 + 64] = 190.5 + 2[95] = 190.5 + 190 = 380.5g/mol
