A sample of methane, CH4, occupies a volume of 341.0 mL at 25°C and exerts a pressure of 975.0 mmHg. If the volume of the gas is allowed to expand to 558.0 mL at 298 K, what will be the pressure of the gas?

A.21.9 mmHg

B.217.0 mmHg

C.7.336*10^-5 mmHg

D.595.8 mmHg

E.4.91 mmHg

    25°C and 298 K are essentially the same temperature, so the expansion was done under constant temperature.

    (975.0 mmHg) x (341.0 mL / 558.0 mL) = 595.8 mmHg

    So answer D.
