A rigid vessel of volume ` 0.50m^(3)` containing `H_(2) ` at `20.5^(@)C` and a pressure of `611 xx 10^(3)` Pa is connected to a second rigid vessel of volume 0.75`m^(3)` containing Ar at `31.2^(@)C` at a pressure of  `433xx10^(3)` Pa. A value separating the two vessels is opened and both are cooled to a temperature of `14.5^(@)C`. What is the final pressure in the vessels?
