Question

A gas has a volume of 300 ml at 30 degree celsius and 730 mm pressure what will be its volume at standard conditions of temperature and pressure

Answer 1

V2=300/1000 l

P2=730/760 atm

T2=300k

At STP , V1=?

P1=1 atm

T1=273 k

P2V2/T2=P1V1/T1 or V1=0.2622 litre

Volume at STP=262.2ml

Hope it helps you
