1. Determine the total number of atoms per molecule:
* C2H3NO has 2 carbon atoms, 3 hydrogen atoms, 1 nitrogen atom, and 1 oxygen atom.
* This gives a total of 2 + 3 + 1 + 1 = 7 atoms per molecule.
2. Use Avogadro's number to convert moles to molecules:
* Avogadro's number states that there are 6.022 x 10^23 molecules in 1 mole of any substance.
3. Calculate the total number of molecules:
* 4 moles of C2H3NO * (6.022 x 10^23 molecules/mole) = 2.409 x 10^24 molecules
4. Calculate the total number of atoms:
* (2.409 x 10^24 molecules) * (7 atoms/molecule) = 1.686 x 10^25 atoms
Therefore, there are approximately 1.686 x 10^25 atoms in 4 moles of C2H3NO.
