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 in \( m \). Which of the following gives the density of the gas?
(a) \( m k T \)
(b) \( p / k T \)
(c) \( \mathrm{pm} / \mathrm{kT} \)
(d) \( p / k T V \)
