Question

A dry gas occupies 127 ml at STP If the same mass of a gas were
collected over water at 23 degree centigrade and a total perrure of
745mm What volume would it ocupy? The vapour pressure of water at
23 deg C is 21mm

Sonia · Answer

This is your answer In this first we find pressure of Dry gas and
then by using P1×V1/T1=P2×V2/T2 We get volume
