`CuSO_(4).5H_(2)O(s)hArrCuSO_(4). 3H_(2)O(s)+2H_(2)O(g), K_(p)=4xx10^(-4)atm^(2)` If the vapour pressure of water is 38 toor then percentage of relatative humidity is :(Assume all data at constant temperture)

A

4

B

10

C

40

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(H_(2)O)=2xx10^(-2)atm`
% relative humidity `=(2xx10^(-2)xx760)/(38)xx100=40%`
