$\text{546.1 g/mol}$

Explanation:

The tin(II) phosphate formula is "Sn"_3("PO"_4)_2. Here the tin ion is $2 +$ and the phosphate ion is $3 -$.

There are 3 atoms of tin, 2 atoms of phosphorus and 8 atoms of oxygen. Multiply the number of atoms by the atomic mass of that atom. Then add them. Units will be grams per mole.

$3 \cdot 118.7 + 2 \cdot 31.0 + 8 \cdot 16 = 356.1 + 62.0 + 128$

$= \text{546.1 g/mol}$
