Okay...Now c, actually KGT saya
P=1/3*density*mean square velocity
When v substitute M/V for density,
P=1/3*Mv^2/V
Note tat if v substitute 4 1 mol of substance,M bcoms molar mass
&using ideal gas eqn PV=RT ,v get
v=3RT/M
Ur confusion is bcoz u don't see its 4 1 mol tat v convert da basic eqn...v dont subst density with a simple mass/volume...but molar mass..
