A g Hydrogen is mixed with `1.2` L if He at STP ina container of volume `20`L If the final temperature is `300K` find the pressure.

Text Solution

Verified by Experts

4 gm Hydrogen =2 moles Hydrogen
and 11.2l. He at S.T.P `=1//2` mole of He
`P=P_(H)=P_(He)=(n_(H)+n_(He))(RT)/V=(2+1//2)(8.3xx(300K))/((20xx10^(-3))m^(3))=3.11xx10^(5)N//m^(2)`
