CORRECT-INCORRECT STATEMENT
A gaseous mixture of \( \mathrm{O}_{2} \) and \( \mathrm{X} \) containing \( 20 \% \) (mole \( \% \) ) of \( \mathrm{X} \), diffused through a small hole in 234 seconds while pure \( \mathrm{O}_{2} \) takes 224 seconds to diffuse through the same hole Which is an incorrect statement?
(1) Average molar mass of the gaseous mixture is 34.921
(2) Molar mass of \( \mathrm{X} \) is 46.6
(3) Molar mass of \( \mathrm{X} \) is 23.3
(4) Vapour density of \( X \) is 23.3
