Calculate the molar mass of 20 L of gas weighing 23.2 g at STP.

Text Solution

Verified by Experts

Molar mass = `(" Weight of the substance x Molar volume")/("Volume of the substance at STP")`
Molar volume at STP = `2.24 xx 10^(2)m^(3)`
= 22.4 L (or) 22400 cc.
Molar mass of the gas at STP = `(23.2xx22.4)/20 `
= 25.984 g .
