Molar Mass of (NH4)2SO4

How to work out the molar mass of (NH4)2SO4

1. Count the atoms of each element in (NH4)2SO4: 2 N, 8 H, 1 S and 4 O.
2. Multiply each count by the element's atomic weight: 2 × 14.007 = 28.014; 8 × 1.008 = 8.064; 1 × 32.06 = 32.060; 4 × 15.999 = 63.996.
3. Add the results: 28.014 + 8.064 + 32.060 + 63.996 = 132.134 g/mol.
