Answer:
The answer to your question is 43.9%
Explanation:
Data
ZnSO₄ 7H₂O
percent of H₂O
Process
- Calculate the molar mass of the molecule
molar mass of ZnSO₄ 7H₂O = 65 + 32 + (14 x 1) + (11 x 16)
= 287g
molar mass of H₂O = (2 x 1) + 16 = 18 g x 7 = 126 g
- Calculate the mass percent of water
287 g ------------------------- 100%
126 g ------------------------- x
x = (126 x 100)/287
x = 43.9 %
