Question

A gas has a volume of 54.0 mL at 475 torr and -13 degrees C . What will be the new volume be at STP?

Answer 1

Answer:35.437 mL

Step-by-step explanation:

Combined gas law

P1V1/T1 = P2V2/T2

P1= 475 torr

V1= 54 mL

T1= 260.15 Kelvin

T2= 273.15 Kelvine

P2= 760 torr

V2=

V2=P1V1T2/(T1P2) m

V2= 475 X 54 X 273.15 / (260.15 X 760) =35.437 mL
