Asample 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

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

idk what is it? is this a question that you know the answer or u dont
