A sample of carbon dioxide at 10.0 ° C has a volume of 300. mL at 760. torr. What is the volume of the gas at 30.0 ° C and 760. torr?

The volume of a gas is directly proportional to its temperature in Kelvin when pressure is constant (Charles's Law). Convert temperatures to Kelvin (10°C = 283K, 30°C = 303K) and use V1/T1 = V2/T2 to find V2: (300 mL / 283 K) = (V2 / 303 K), solving gives V2 ≈ 321 mL.
