Answer 1

pressure of N₂ = 5.37 atm

Explanation

mass N₂ = 32.0

moles N₂ = (mass N₂) / (molar mass N₂)

moles N₂ = (32.0 g) / (28.0 g/mol)

moles N₂ = 1.143 mol

According to ideal gas law,

pressure N₂ = [(moles N₂) * (R) * (temperature N₂)] / (volume N₂)

where temperature N₂ = 13.3 ^oC = 286.3 K

R = constant = 0.0821 L-atm/mol-K

volume N₂ = 5.00 L

pressure N₂ = [(1.143 mol) * (0.0821 L-atm/mol-K) * (286.3 K)] / (5.00 L)

pressure N₂ = 5.37 atm
