1. Calculate molar masses (using atomic masses Zn = 65.38, P = 30.974, O = 15.999 g·mol−1):

- Zn: 3 × 65.38 = 196.14 g
- P: 2 × 30.974 = 61.948 g
- O: 8 × 15.999 = 127.992 g

2. Total molar mass = 196.14 + 61.948 + 127.992 = 386.08 g·mol−1

3. Percent composition:
- %Zn = 196.14 / 386.08 × 100 = 50.80%
- %P = 61.948 / 386.08 × 100 = 16.05%
- %O = 127.992 / 386.08 × 100 = 33.15%

(Values rounded to two decimal places.)
