how many c atoms are contained in 15.63g of c5h12??

asked by rose
  1. You have to find the mass of 1 mole first. Then you will know what fraction of a mole you are working with

    one mole has 5 carbons

    your fraction of a mole has ? carbons

  2. 5* 12.01+ 12*1.01= 60.05 g/mol
    c H
    1 mol of C= 60.05g/mol

    next step?
