हिन्दीHow much copper can be obtained from \( 100\text{ g} \) of copper sulphate (\( \text{CuSO}_4 \))? (Atomic masses: \( \text{Cu} = 63.5, \text{S} = 32, \text{O} = 16 \))
Correct answer · Option 2
39.81 g
Explanation
Molar mass of \( \text{CuSO}_4 = 159.5\text{ g mol}^{-1} \). Mass of Cu = \( \frac{63.5}{159.5} \times 100 = 39.81\text{ g} \).
