Vedclass · Answer

(C) The atomic mass of nitrogen is $14 \ g/mol$.The mass of $6.022 	imes 10^{23}$ atoms of nitrogen is $14 \ g$.Therefore,the mass of $2 	imes 10^{22}$ nitrogen atoms is calculated as:$	ext{Mass} = \frac{14 \ g}{6.022 	imes 10^{23} \ 	ext{atoms}} 	imes 2 	imes 10^{22} \ 	ext{atoms}$$	ext{Mass} \approx \frac{14}{6} 	imes 10^{-1} \ g$$	ext{Mass} \approx 2.333 	imes 0.1 \ g = 0.233 \ g$ (Note: Using $6 	imes 10^{23}$ as an approximation for Avogadro's number as per the provided solution logic gives $0.467 \ g$).

The mass of $2 \times 10^{22}$ nitrogen atoms is ..... grams.
