A sample of an ideal gas has a volume of 3.55 L at 14.60 ∘C and 1.90 atm. What is the volume of the gas at 19.80 ∘C and 0.990 atm?

A sample of an ideal gas has a volume of 3.55 L at 14.60 ∘C and 1.90 atm. What is the volume of the gas at 19.80 ∘C and 0.990 atm?

Answer 1

Hello again! For this one, we're using the combined gas law P₁V₁/T₁ = P₂V₂/T₂, rearranged to solve for V₂ and converting temperature to Kelvin:

V₂ = P₁V₁T₂/T₁P₂ ---> V₂ = (1.9 atm)(3.55 L)(292.8 K)/(287.6 K)(0.99 atm) = 6.94 L

Let me know if this makes sense!
