1. At STP, Volume of 1 mol of a gas occupies volume of 22.4 L

ratio of 1 mol : 22.4

then 4.2 mol : x .....(cross multiply )

4.2 mol * 22.4 L= x mol.L

x = 94.08 L

Alternatively, you can say :

1 mol = 22.4 L

Volume of 4.2 mol = (4.2mol Ne * 22.4L )/1 mol Ne = 94.08

Option C is the correct ans
