Question

Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0 L. What
temperature must be maintained on 0.500 moles of this gas in order to maintain this pressure? Express
the temperature in degrees Celsius.

Answer 1

pV=nRT;

p=123 kPa;

V=10.0 L;

n=0.500 mol

R=8.314;

T - ?

T=pV/nR=123*10/(0.5*8.314)=295.9 K = 22.9 ^oC

Answer: 22.9 ^oC
