Axel George · Answer 1

We will use the combined gas equation.

The final volume V₂=931.74 mL

Explanation:

The combined gas equation shows the interrelationship between the volume, the pressure and the absolute temperature of a fixed mass of an ideal gas,

P₁V₁/T₁=P₂V₂/T₂

Because we are looking for the volume after the initial conditions havre been varied, we will call this volume, volume 2 (V₂)

Let us make it the subject of the equation.

V₂ = (P₁V₁T₂) T₁P₂

P₁=1.50 ATM

P₂=1.20 ATM

V₁=800 mL

V₂=?

T₁ = (20+273) K=293 K

T₂=0+273 K=273 K

V₂ = (1.50 * 800*273) / (293*1.2)

V₂=931.74 mL
