What is the mass of 2g atoms of N?

To find the mass of 2 grams of nitrogen (N) atoms, we first recognize that the Atomic Mass of nitrogen is approximately 14 grams per mole. Therefore, 2 grams of nitrogen corresponds to about ( \frac{2 , \text{g}}{14 , \text{g/mol}} \approx 0.143 , \text{moles} ) of nitrogen atoms. This means we have approximately ( 0.143 \times 6.022 \times 10^{23} \approx 8.6 \times 10^{22} ) nitrogen atoms in 2 grams.
