Moles per litre measures concentration C of solution. C =( n / V )=( P / RT )

Q. ' $n$ ' moles of an ideal gas at temperature $T$ (in Kelvin) occupy ' $V$ ' litres of volume, exerting a pressure of ' $P$ ' atomospheres. What is its concentration (in mol $L^{- 1}$ )?
$(R =$ gas constant $)$

P/RT

PT /R

RT/P

R /PT

Moles per litre measures concentration C of solution.
$C = \frac{n}{V} = \frac{P}{RT}$
