Ammonia molecules have three hydrogen atoms and one nitrogen atom. How many of each atom arein five molecules of ammonia

Now 1 mole of ammonia also contains 6.022 * 10^23 molecules of ammonia. In one molecule of ammonia, we have 1 nitrogen atom and 3 hydrogen atom. Hence a total of 4 atoms, so in 6.022 * 10^23 molecules of ammonia we will have 4 * 6.022 * 10^23 number of atoms.
