Ideal gas law combined gas law

Question

A gas sample at 40.0C has a volume of 62.0 L when under a pressure of 0.82 atm. What is the new volume if the pressure is increased to 2.02 atm. and the temperature decreases to 10.0C? (Kelvin temperature conversion, T = C + 273)

1. 
   

Answer 1

It's the combined gas law

make sure pressure units match

make sure volume units match

make sure temperatures are in K

P1V1/T1=P2V2/T2

0.82(62)/(40+273.15)=2.02V/(10+273.15)

Solve for V
