Question: how many atoms are present in 2.00 mol of nitrogen gas n2?
Answer: 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. Hope it will be helpful.
