Solution

The correct option is C $n$ moles of the gas have a volume $V$
$(B)$ $n$ moles of the gas have a volume $V$
An ideal gas is a gas whose pressure $P$ , volume $V$ , and temperature $T$ are related by the ideal gas law i.e.
$P V = n R T$ ,
where $n$ is the number of moles of the gas and $R$ is the ideal gas constant.
