How many molecules of atoms of each element are there in one mole of ammonium carbonate?

The formula for ammonium carbonate is (NH4)2CO3.

In one mole of ammonium carbonate, there will be two moles of nitrogen, eight moles of hydrogen, one mole of carbon, and three moles of oxygen. There are 6.02x1023 atoms per mole. So, for one mole of ammonium carbonate there are:

2 mol N * 6.02x1023 atoms per mole = 1.20x1024 atoms of nitrogen

8 mol H * 6.02x1023 atoms per mole = 4.82x1024 atoms of hydrogen

1 mol C * 6.02x1023 atoms per mole = 6.02x1023 atoms of carbon

3 mol O * 6.02x1023 atoms per mole = 1.81x1024 atoms of oxygen
