Acylinder with a moveable piston contains 0.87 mol of gas and has a volume of 334 ml. what will its volume be in an additional 0.22 mol of gas is added to the cylinder?

418.46 ml.

Explanation:

V = n x constant.

∴ V₁n₂ = V₂n₁

V₁ = 334 ml, n₁ = 0.87 mol, V₂ = ??? ml, n₂ = (0.22 + 0.87) = 1.09 mol.

∴ V₂ = (V₁n₂) / n₁ = (334 ml)(1.09 mol) / (0.87 mol) = 418.46 ml.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
