Question

A sample of helium has a volume of 3 liters when the pressure is 500 torr. What volume does the gas occupy at 300 torr?

Answer 1

The volume of the gas is 5 liters. See the explanation below , please.

Step-by-step explanation:

We use the Boyle-Mariotte´s Law (we consider that the temperature is constant according to the given statement):

P initial x V initial = P final x V final

500 torr x 3 liters = 300 torr x V final

V final= (500 torr x 3 liters)/300 torr = 5 liters
