The ideal gas law is an example of an equation of state that shows how the different state

variables are related at equilibrium.

Which of the following options gives an equation for the pressure of an ideal gas at

equilibrium in terms of the temperature $(T),$ volume $(V),$ mass of the gas $(m),$ and molecular

weight of the gas $($M$)?$

$P=(\frac{M}{m}V{)}^{**}RT$

$P=(\frac{m}{M}V)**RT$

$P=(m\frac{V}{M}{)}^{**}RT$

$P=(M\frac{V}{m}{)}^{**}RT$
