Question

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

Answer 1

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.
