Answer:

28.2 kPa

Explanation:

This is a question for the Ideal Gases Law:

P . V = n . R . T → P = (n . R . T) / V

Let's replace data:

P = (0.540 mol . 0.082 L.atm/mol.K . 223 K) / 35.5 L

P = 0.278 atm

We convert the unit of pressure from atm to kPa

0.278 atm . 101.3 kPa / 1atm = 28.17 kPa ≅ 28.2 kPa
