Question

A 40.0L tank of ammonia has a pressure of 12.7kPa. Calculate the volume of the ammonia if its pressure is changed to 8.4 kPa while its temperature remains constant

Answer 1

60.5 L

Step-by-step explanation:

If the gas temperature is constant, we can use Boyle's law:

P1V1 = P2V2

V2 = P1V1 / P2

P1 = 12.7 kPa

V1 = 40.0 L

P2 = 8.4 kPa

V2 = (12.7 kPa) (40.0 L) / (8.4 kPa) = 60.5 L
