A balloon containing 0.500 mol Ar at 0.00°C and 65.0 kPa pressure is expanded by adding more argon.

Formula: PV = nRT (R = 8.31 L•kPa/mol•K)

What is the original volume of the gas?

L

Use V = nRT/P.

V = (0.500 mol)(8.31 L·kPa·mol⁻¹·K⁻¹)(273.15 K) / (65.0 kPa)
= 1134.94 / 65.0
= 17.5 L (to three significant figures).
