    3. a.

    (3.50 × 10^22 molecules) / (6.02214 × 10^23 molecules/mol) ×

    (44.0956 g C3H8/mol) = 2.56 g C3H8

    b.

    (3.50 × 10^22 molecules) / (6.02214 × 10^23 molecules/mol) × (22.414 L/mol) =

    1.30 L

    c.

    (3.50 × 10^22 molecules) × (8 atoms H / 1 molecule C3H8) = 2.80 × 10^23 atoms H

    d.

    (3.50 × 10^22 molecules) × (3 atoms C / 1 molecule C3H8) = 1.05 × 10^23 atoms C

    a. 3.50X10^22 molecules / 6.022X10^23 molecules/mole = 0.0581 mol C3H8

    b. 0.0581 mol X 22.414 L/mol = 1.30 L

    c. 3.50X10^22 molecules X (8 H atoms/molecule) = 2.80X10^23 H atoms

    d. 3.50X10^22 molecules X (3 C atoms/molecule) = 1.05X10^23 C atoms
