How are the density and molar mass of a gas related?

Text Solution

Verified by Experts

`Pv= n RT `
` Pv = (w)/( m ) RT `
` p = (w/v) (RT)/(M )`
Molar mass ` M= (dRT)/(P ) [ therefore (w)/(v ) =` density (d)]
P = Pressure of gas
R = Universal gas constant
T = Temperature of gas in kelvin.s scale.
