huge chemistry question, double points for correct answer?

A gas has a volume of 4.5 L at STP. If the conditions are changed to SATP, what is the new volume of the gas?

First list all the variables. Enter ? for the unknown variable.

P1 = kPa

T1 = degrees Celius or K

T2 = degrees Celius or K

V1 = L

V2 =L

    STP - Standard Temperature and Pressure - is defined by IUPAC (International Union of Pure and Applied Chemistry) as air at 0oC (273.15 K, 32 oF) and 100 kPa

    SATP - Standard Ambient Temperature and Pressure is a reference with temperature of 25 degC (298.15 K) and pressure of 101 kPa.

    Using combined gas law equation,

    p1V1/T1 = p2V2/T2

    Or, 100*4.5/273 = 101*V2/298

    So final volume, V2= 4.86 L
