Question

The volume of a gas at 800mm Hg pressure and 30°C is 480ml.
What volume does the gas occupy at STP?​

Answer 1

Answer:

You can use the “combined gas law” to solve this problem:

P1V1/T1 = P2V2/T2

P1 = initial pressure (ie; 800 mmHg)

V1 = initial volume (ie; 480 mL)

T1 = initial Kelvin temperature (ie; 30 C = 303 K)

P2 = final pressure (ie; 760 mmHg)

V2 = final volume (ie; unknown)

T2 = final Kelvin temperature (ie; 273 K)
