Computing Molar Mass of Zinc Phosphate Step by Step

Molar Mass of Zinc Phosphate: Step-by-Step Calculation

1. Identify Element Counts

Read Zn3(PO4)2 and list how many atoms of each element are present:

  1. 3 atoms of Zinc (Zn)
  2. 2 atoms of Phosphorus (P)
  3. 8 atoms of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Zinc (Zn) ~= 65.380 g/mol
  2. Phosphorus (P) ~= 30.974 g/mol
  3. Oxygen (O) ~= 15.999 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Zinc (Zn): 3 x 65.380 = 196.140 g/mol
  • Phosphorus (P): 2 x 30.974 = 61.950 g/mol
  • Oxygen (O): 8 x 15.999 = 127.990 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (3 x 65.380 + 2 x 30.974 + 8 x 15.999)

Molar Mass = 196.140 + 61.950 + 127.990

Molar Mass = 386.080 g/mol

Final rounded value shown on this page: 386.08 g/mol.
