Volume of 1 mole of N2 at 30 c and 1.2 ATM

We should indicate first and foremost the assumption of ideal gas behavior so that we can use the ideal gas equation written below:

PV = nRT

For this problem, let's solve for V. Rearranging the equation,

V = nRT/P

Substituting the values,

V = (1 mol) (0.0821 L-atm/mol-K) (30 + 273 K) / 1.2 atm

V = 20.73 L of N₂ gas
