Question

If P, V, M, T and R are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by.

A

$\frac { R T } { P M }$

B

$\frac { P } { R T }$

C

$\frac { M } { V }$

D

$\frac { P M } { R T }$

Answer

$\frac { P M } { R T }$

Explanation

Solution

$P V = n R T = \frac { m } { M } R T$

$\therefore \frac { m } { V } = \frac { P M } { R T } =$ density
