Consider three sealed steel tanks, labeled X, Y, and Z. Each tank has the same volume and the same temperature. In each tank, one mole of CH₄ is represented by a circle, one mole of oxygen by a square, and one mole of SO₂ by a triangle. Assume that no reaction takes place between these molecules.

(a) In which tank is the total pressure highest?

(b) In which tank is the partial pressure of SO₂ highest?

(c) In which tank is the mass of all three gases the same?

(d) Which tank has the heaviest contents?
