Question

What is the mass of h20in 1000kg of cuso4.10h20

Answer 1

Molecular Mass of $CuSO_{4}.10H_{2}O$= 340g = 0.34kg.
Mass of $H_{2}O$ in that = 180g = 0.18kg.

Therefore, using unitary method,

In 0.34kg of $CuSO_{4}.10H_{2}O$, there is 0.18kg of $H_{2}O$,

Hence in 1000kg of $CuSO_{4}.10H_{2}O$, there will be:-

$\frac{1000 *0.18}{0.34}$ kg of $H_{2}O$
= 529.411 kg of $H_{2}O$
