Answer:
[tex]5.33\text{ }\times\text{ 10}^{30\text{ }}\text{ moles}[/tex]Explanation:
Here, we want to get the number of moles of nitrogen
Mathematically:
[tex]1\text{ mole of nitrogen = 6.02 }\times\text{ 10}^{23}\text{ atoms}[/tex]3.21 * 10^54 atoms of nitrogen will contain:
[tex]\frac{3.21\times10^{54}}{6.02\text{ }\times\text{ 10}^{23}}\text{ = 5.33 }\times\text{ 10}^{30\text{ }}\text{ moles}[/tex]
