# chem. Combined Gas laws

posted by .

A gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299K. If I raise the temperature to 350K and lower the pressure to 1.5 atm, what is the new volume of the gas?

Use the combined gas law here. I will be happy to critique your work.

• chem. Combined Gas laws -

v2=p1v1t2
p2t1

v2=(2.3atm)(17L)(300K)
(1.5atm)(299K)

v2=11,730
448.5
v2=26.16

• chem. Combined Gas laws -

(2.3 * 17) * 350 = 13685
299 * 1.5 = 448.5
13685 / 448.5 = 30.5
v2 = 30.5L
