Question

No. Of atom in 10g of ammonia

Answer 1

Here we are talking about ammoniawhich is a molecule. Now 1 mole ofammonia also contains 6.022 * 10^23 molecules of ammonia. In onemolecule 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.
