Calculate the density (in g/L) of a gas mixture at 37.5°C and 654 mmHg composed of 62.0%  Kr(g) and 38.0% Cl₂(g) by volume.

The following pressure-density data was obtained for an unknown gas at 60 °C.

Using this data, calculate the molar mass of the gas. Start by drawing a graph of d/P against P.

At 36.9°C and 786 torr, a 67.0 mL sample of liquid pentane (density = 626 g/L) evaporated inside an empty tank. Calculate the volume of the tank.

At 424°C and 65.0 kPa, the density of citronella, a mosquito repellant, is 1.73 g · L⁻¹. Calculate the molar mass of citronella.

An 11.5-mL sample of liquid butane (density = 0.573 g/mL) is evaporated in an otherwise empty container at a temperature of 28.5 °C. The pressure in the container following evaporation is 892 torr. What is the volume of the container?
