1.0 mole of pure dinitrogen gas at SATP conditions was put into a vessel of volume 0.025 cm^(3), maintained at the temperature of 50^(@)C, what is the preussre of the gas in the vessel ?

<P>

Solution : Volume of `1.0` mol of a gas at SATP `(V_(1))=24*8XX10^(-3)m^(3)`
intial condition (SATP) `""` Final condition
`V_(1)=24*8xx10^(-3)m^(3)"" V_(2)=0*1 m^(3)`
`P_(1)1 "bar""" P_(2) ?`
`T_(2)298*15 k"" T_(2)50^(@)C323*15K`
Acoording to general gas equation.
`(P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2)) or P_(2) =(P_(1)V_(1)T_(2))/(T_(1)V_(2))`
`:. P_(2)=(1*0xx24*8xx10^(-3)xx323*15)/(298*15xx0*25)=1*076` bar
`:. P_(2) =1*076` bar
