    The answer is: the mass of carbon is 420.6 grams.

    m (C₈H₁₈) = 500 g; mass of octane.

    M (C₈H₁₈) = 114.22 g/mol; molar mass of octane.

    n (C₈H₁₈) = m (C₈H₁₈) : M (C₈H₁₈).

    n (C₈H₁₈) = 500 g : 114.22 g/mol.

    n (C₈H₁₈) = 4.38 mol; amount of octane.

    In one molecule of octane, there are eight carbon atoms:

    n (C) = 8 · n (C₈H₁₈).

    n (C) = 8 · 4.38 mol.

    n (C) = 35.02 mol; amount of carbon.

    m (C) = 35.02 mol · 12.01 g/mol.

    m (C) = 420.6 g; mass of carbone.
