    Answer:

    18.45 g of C

    Explanation:

    This is a problem of rules of three:

    1 mol of C₃H₈ contains 3 moles of C and 8 moles of H

    If 8 moles of H are contained in 1 mol of propane

    4.10 moles of H are contained in (4.1 . 1) /8 = 0.5125 moles

    Now, If 1 mol of propane contains 3 moles of C

    0.5125 moles of propane may contain (0.5125 . 3) / 1 = 1.5375 moles of C

    Let’s convert the moles to mass:

    1.5375 mol . 12 g /mol = 18.45 g
