Question

I just wanted the know the number of atoms on 3N2

Answer 1

use avogadro's number: \(6.022 \times 10^{23}\) \(\large\frac{atoms}{mole}\)

Answer 2

The question is slightly vague, but if 1 molecule of N2 has 2 N atoms, then 3 molecules will have 3molecules * 2(atoms/molecule) or 6 atoms total. If it's 3 MOLES of N2, then use @abb0t 's approach above

Answer 3

Thanks
