If 250 mL of \[{{N}_{2}}\]  over water at \[30{}^\circ C\] and a total pressure of 740 torr is mixed with 300 mL of Ne over water at \[25{}^\circ C\] and a total pressure of 780 torr, what will be the total pressure if the mixture is in a 500 mL vessel over water at \[35{}^\circ C\]? Given: vapour pressure (Aqueous tension) of \[{{H}_{2}}O\] at \[25{}^\circ C\], \[30{}^\circ C\] and \[35{}^\circ C\] are 23.8, 31.8 and 42.2 torr respectively Assume volume of  \[{{H}_{2}}O(l)\] is negligible in final vessel)
