Question

The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 L?

Use: P1V1=P2V2

A) 0.225 atm
B) 0.444 atm
C) 2.25 atm
D) 4.44 atm

Answer 1

A) 0.225atm

Step-by-step explanation:

P1V1 = P2V2

V1 = 450ml

P1 = 1.0atm

V2 = 2L = 2 X 100 = 2000ml

P2 =?

1.0 X 450 = P2 X 2000

P2 = (1.0 X 450)/2000

= 0.225atm
