1. Determine the total number of atoms per molecule:
* SO3 has 1 sulfur atom (S) and 3 oxygen atoms (O), for a total of 4 atoms per molecule.
2. Use Avogadro's number:
* Avogadro's number tells us that there are 6.022 x 10^23 particles (atoms, molecules, etc.) in one mole of a substance.
3. Calculate the number of atoms:
* Step 1: Multiply the moles of SO3 by Avogadro's number to find the number of SO3 molecules: 1.14 mol SO3 * (6.022 x 10^23 molecules/mol) = 6.86 x 10^23 molecules SO3
* Step 2: Multiply the number of SO3 molecules by the number of atoms per molecule: 6.86 x 10^23 molecules SO3 * (4 atoms/molecule) = 2.74 x 10^24 atoms
Therefore, there are approximately 2.74 x 10^24 atoms in 1.14 mol of SO3.
