Question

A sample of hydrogen gas H2 has a volume of 5.0 L and a pressure of 1.0 atm. What is the final pressure in atmospheres if the volume is decreased to 2 L with no change in temperature and amount of gas

Answer 1

2.5 atm

Step-by-step explanation:

P = Pressure

V = Volume

P1V1 = P2V2

1 x 5 = P2 x 2

5 = P2 x 2

Divide both sides by 2

5/2 = P2 x 2/2

P2 = 2.5
