Question: how many atoms are in 2 moles of nitrogen?
Answer: 1 mole = 6.022 x 10^23 atoms or molecules or formula units of that substance. Calculation of mole from number of particles and vice – versa. Here, 2 moles of N2 molecules will have 2x2 moles of N atoms or particles. So, 4 mole of N atoms = 4 x 6.022 x 10^23 atoms of Nitogen.
