1 mole of C₃H₈ contains 3 moles of C atoms and 8 moles of H atoms.
For 3 moles of C atoms, total number of moles of atoms = (3 + 8) mol = 11 mol
Total number of atoms that the sample contains = (17.0 mol) × (11/3) = 62.3 mol
For 3 moles of C atoms, total number of moles of atoms = (3 + 8) mol = 11 mol
Total number of atoms that the sample contains = (17.0 mol) × (11/3) = 62.3 mol
