Answer:

262.8582 g/mol in Magnesium Phosphate

Explanation:

Magnesium Phosphate is #Mg_3(PO_4)_2#
Given this, we can figure that each element of:

Mg = 24.305 g/mol
P = 30.974 g/mol
O = 15.9994 g/mol

based on our chemical formula for Magnesium Phosphate, we have:

3 x Mg = 72.915
2 x P = 61.948
8 x O = 127.9952

Add these values up and we get:

Molar Mass of Magnesium Phosphate = 262.8582 g/mol.

or more simply: 262.9 rounded.
