calculate the empirical formula. A chemist heats 50.00g of sulfur under controlled conditions to produce a sulfer-oxygen compund.The mass of the sulfur-oxygen compound is 100.00g. What is the empirical formula of the sulfur-oxygen?

  • Chemistry -

    S + O2 ==> SxOy
    S start = 50.00 grams.
    SxOy = 100.00 grams.
    Therefore, we must have added 50.00 g oxygen.

    mols S = 50/32.066 = 1.56
    moles O = 50/16 = 3.125
    Now find the ratio of the two to each other. The easy way is to divide the smaller number by itself.
    1.56/1.56 = 1.000 (you do this to get 1.00 and it works every time. :-),

    Then divide the other number by the same small number.
    3.125/1.56 = 2.004.
    Now round those to whole numbers and you have the formula of S1O2 or SO2.
