A given mass of gas occupies a volume of 449 mL at 25°C and 740 mmHg. What will be the new volume at STP?

  • chemistry -

    Use the combined gas law:

    P2V2/T2= P1V1/T1

    V2=P1V1T2/P2T1

  • chemistry -

    Using the gas equation,
    V1=499ml; T1=25C+273K=298
    P1=740mmHg
    At s.t.p
    P2=760mmHg; T2=273K; V2=?
    V2= 499*740*273 /760*298
    =445.1 ans
