How many moles.....
This one is easy enough to do in your head. No set-up required.
The subscripts in a chemical formula give the number of moles of each element in 1 mole of the compound. In 1 mole of N2O4 there are 2 moles of N and 4 moles of O. Therefore, in 3.62 mol of N2O4 the number of N moles will twice that: 7.24 mol N.

Refer to the subscripts in the chemical formula of N₂O₄.
Each mole of N₂O₄ contains 2 moles of N atoms and 4 moles of O atoms.
Moles of N atoms in 3.62 moles of N₂O₄ = (3.62 mol) × 2 = 7.24 mol
