A sample of an ideal gas has a volume of 2.23 L at 289 K and 1.07 atm. Calculate the pressure when the volume is 1.16 L and the temperature is 301 K.

Answer 1

Hi Emily! For this one, we're going to use the combined gas law: P₁V₁/T₁ = P₂V₂/T₂, and we'll rearrange it to solve for P₂:

P₂ = P₁V₁T₂/T₁V₂ ---> P₂ = (1.07 atm)(2.23 L)(301 K)/(289 K)(1.16 L) = 2.14 atm

Hope this helps! Let me know if you have any questions!
