The one which has smallest number of molecules is : A) 0.1 mol of CO2 gas B) 11.2 of CO2 gas at N.T.P. C) 22 g of CO2 gas D) 22.4 Ă— 103 ml of CO2 gas

Answer 1

0.1 mol CO2 = 0.1 Na molecules

11.2 litres CO2 = 0.5 Na molecules

22 gm CO2 = 0.5 Na molecules

22.4 * 10^3 ml CO2 = 1 Na molecules

Hence

Option D is correct

I hope it helps you:)
