A sample of N2 gas occupying 800.0 mL at 20.0°C is chilled on ice to 0.00°C. If the pressure also drops from 1.50 atm to
1.20 atm, what is the final volume of the gas?
Which equation should you use

Answer:

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
