Question

calculate the molar mass of Calcium phosphate

Answer 1

2 phosphorus moles at 31g per mole=62g
8 oxygen moles at 16g per mole = 128g
So molar mass of calcium phosphate is 120g+62g+128g=310g

Answer 2

formula will be ca3(po4)2
therefore.
as we know that the mass of calcium is 40 where is the mass of one molecule of oxygen is 16 and the mass of one molecule of phosphorus is 30.
now we find value of moleculer mass
3*40+2*31+8*16=120+62+128=310g
