What is the volume occupied by `30 1 xx 10^(23)` molecules of carbon dioxide gas at STP? Calculate the mass of this gas.

Text Solution

Verified by Experts

Number of molecules = `30.1 xx 10^(23)`
Number of moles of gas =`(30.1 xx 10^(23))/(6.023 xx 10^(23)) =5` moles
Volume occupied by 5 moles of gas = `22.4 xx 5 = 112` L
Mass of the given gas = Number of moles `xx GMW = 5 xx 44 = 220` g .
