A compound of molecular weight 70.1 has the following composition: Carbon 85.63% and hydrogen 14.37%. What is the empirical formula? What is the molecular formula?

  • Chemistry - ,

    70.1*.8563/12 = 5.00 moles C
    70.1*.1437/1 = 10.07 moles H

    empirical CH2 has mol wt 14

    70.1/14 = 5, so

    molecular formula is C5H10
