Determine the number of molecules present in 4.56 mol of nitrogen (n2).

We can calculate this by using Avogadro's number which is 6.022 x 10²³.

1 mole of nitrogen contains = 6.022 x 10²³ molecules

4.56 moles of nitrogen contains = 4.56 x 6.022 x 10²³

2.75 x 10²⁴ molecules are present in 4.56 moles of nitrogen.
