if 0.225 mol of tin combined with 0.450 mol sulfur, what is the empirical formula of the tin sulfide product?

  • chemistry -

    moles Sn = 0.225
    moles S = 0.450
    ratio. divide by smallest number to make it 1.00
    Sn = 0.225/0.225 = 1.00
    S = 0.450/0.225 = 2.00
    empirical formula is Sn1S2. Of course the 1 is not needed so it is SnS2.
