Question

The kinetic theory of gases gives the formula $PV=\frac{1}{3}Nm{v}^2$ for the pressure $P$ exerted by a gas enclosed in a volume $V.$ The term $Nm$ represents

• A. the mass of a mole of the gas
• B. the mass of the gas present in the volume $V$
• C. the average mass of one molecule of the gas
• D. the total number of molecules present in volume $V$

Answer 1

Answer: (B)

'$Nm$’ represents mass of gas in volume $V$, as $N$ represent number of molecules and $m$ represents mass of a molecule.
