If 250 ml. of N2 over water at 30°C and ...

If 250 ml. of `N_2` over water at 30°C and a total pressure of 740 torr is mixed with 300 mL of Ne over water at 25°C and a total pressure of 780 torr, what will be total pressure if the mixture is in a 500 mL vessel over water at 35 °C. (Given : Vapour pressrue (Aqueous tension) of `H_2O` at 25°C, 30°C and 35°C are 23.8, 31.8 and 42.2 torr respectively. Assume volume of `H_2O` (l) is negligible in final vessel)

A
