Chemistry - Chemical Equilibrium Question with Solution | TestHub

At 450 K , Calculate the mass of ${\mathrm{H}}_2\mathrm{O}$ present (in gm) in a 10 litre closed vessel which contains only ${\mathrm{CuSO}}_4\cdot 5{\mathrm{H}}_2\mathrm{O}$ crystal initially.

Given:

$$\begin{gathered} \text{displaylines}CuS{O}_4\cdot 5H_{2}O(s)\to CuS{O}_4(s)+5H_{2}O(g) \\ {K}_p=3.2\times 10^{-4}at{m}^5 \end{gathered}$$

Take $\mathrm{R}=0.08\mathrm{atm}$ litre $/\mathrm{mol}\mathrm{K}$
