A) > 7.92
B) < 7.92
C) equal to 7.92
D) 0.822
Correct Answer: B
Solution :
[b] \[{{K}_{p}}=p_{{{H}_{2}}O}^{2}=1.086\times {{10}^{-4}}\,at{{m}^{2}}\] \[{{p}_{{{H}_{2}}O}}=1.04\times {{10}^{-2}}\times 760=7.92\,\,\text{mm}\,\text{Hg}\] If the vapour pressure of water in air is less than 7.92 mm Hg, water of crystallization is given out.You need to login to perform this action.
