A sample of argon gas has a volume of 715 mL at a pressure of 1.34 atm and a temperature of 144 Celsius.

Question

What is the volume of the gas in milliliters when the pressure and temperature of the gas sample are changed to 622 mmHg and 321 K?

Answer 1

(P1V1)/T1 = (P2V2)/T2

Use Kelvin for both T1 and T2. You will need to change the pressure to the same units--it makes no difference which one you change.

Answer 2

902 mL

Answer 3

I obtained 901 mL
