What is the molecular mass of ammonium phosphate, (NH4)3PO4? Round your answer to the second decimal place.

Answer 1

Answers (rounded to 2 decimal places)

- Sn(CO3)2:
Sn = 118.71
2 C = 2 × 12.01 = 24.02
6 O = 6 × 16.00 = 96.00
Total = 118.71 + 24.02 + 96.00 = 238.73 g/mol

- (NH4)3PO4:
3 N = 3 × 14.01 = 42.03
12 H = 12 × 1.008 = 12.10
P = 30.97
4 O = 4 × 16.00 = 64.00
Total = 42.03 + 12.10 + 30.97 + 64.00 = 149.10 g/mol
