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?NEET 2016 (Phase 2)

Options:

Answer:

Solution:

$PV = nRT \Rightarrow PV = (\frac{m}{M}) RT$

$P = (\frac{R}{M}) \frac{m}{V} T \Rightarrow \frac{P}{ρ} = (\frac{R}{m N_{A}}) T$

$\Rightarrow \frac{P}{ρ} = \frac{k T}{m}$

$ρ = \frac{P m}{k T}$ .
