A certain vessel `X` has water and nitrogen gas at a total pressure of 2 atm and `300 K`. All the contents of vessel and transferred to another vessel `Y` having half the capacity of the vessel `X`. The pressure of `N_(2)` in this vessel was 3.8 atm at `300 K`. The vessel `Y` is heated to `320 K` and the total pressure observed was 4.32 atm. Assume that the volume occupied by the gases in vessel is equal to the volume of the vessel. Calculate the following:
Pressure of `H_(2)O` in `X` at `320 K`.

Options

A. `0.1`
B. `0.2`
C. `1.0`
D. `2.0`

Answer

A

Explanation

Pressure of `N_(2)` in `X = 1.9 atm
Total pressure of vessel X=2 atm
`:.` Pressure of `H_(2)O(g)` in `X` at `300 K =2-1.9 =0.1 "atm"`
