Question:

A given sample of an ideal gas occupies a volume V at a pressure P and absolute temperature T. The mass of each molecule of the gas is m. Which of the following gives the density of the gas?

Options:

\(\frac{P}{kT}\)

\(\frac{mP}{kT}\)

\(\frac{P}{kTV}\)

mkT

Correct Answer:

\(\frac{mP}{kT}\)

Explanation:

\(\frac{P}{\rho} = \frac{kT}{m}\)

\(\rho = \frac{mP}{kT} \)
