Vedclass · Answer

(C) For the $1^{st}$ jar:Number of moles of $H_2 = \frac{2 \ g}{2 \ g/mol} = 1 \ mol$.Number of molecules of $H_2 = 1 	imes N_A = 6.022 	imes 10^{23}$ molecules.For the $2^{nd}$ jar:Number of moles of $N_2 = \frac{28 \ g}{28 \ g/mol} = 1 \ mol$.Number of molecules of $N_2 = 1 	imes N_A = 6.022 	imes 10^{23}$ molecules.Since both jars contain $1 \ mol$ of gas,they contain the same number of molecules.
