How many atoms are in 2 moles of ammonia?

Answer: Therefore 2 moles will have 1.204*10^24 molecules of NH3. There are 4 atoms in each molecule, so 2 moles will have 4*(1.204*10^24) atoms which is 4.816*10^24 atoms.

What is the total number of atoms in 1.0 mole of co2?

Let’s consider the carbon dioxide molecule. We know it has the formula CO2, and this tells us that: 1 mole carbon dioxide contains 6.02 x 1023 molecules. 1 mole of carbon atoms per mole of carbon dioxide = 6.02 x 1023 carbon atoms.
