A vessel has nitrogen gas and water vapour at a total pressure of 1 atm. The partial pressure of water vapour is `0.3 atm`. The contents of this vessel are transferred to another vessel having one-third the capacity of the original vessel, completely at the same temperature. The total pressure of the system in the new vessel is

Options

A. 2.4 atm
B. 1 atm
C. 3.33 atm
D. 0.3 atm

Answer

A

Explanation

`P_(s) = 0.7 P_(H_(2) O)^(O) = 0.3 ` , volume `(1)/(3) ` , then `P_(g) = 2.1 " "` Total `P = 2.1 + 0.3 = 2.4`
