Question

$ 1 \,g$ -atom of nitrogen represents:

• A. $6.02 \times 10^{23} N _{2}$ molecules
• B. $22.4 L$ of $N _{2}$ at S.T.P
• C. $11.2 L$ of $N _{2}$ at S.T.P
• D. $28 \,g$ of nitrogen

Answer 1

Answer: (C)

$1 \,g$ - atom of nitrogen $=6.02 \times 10^{23} N$ atoms

$1 mol$ of $N =1 / 2$ mole of $N _{2}=11.2 L$ at $S.T.P$
