    1. The problem statement, all variables and given/known data
    10.00 g of tin (Sn) is heated in air 12.69 g of the oxide is produced. Calculate the equivalent weight of the tin.

    2. Relevant equations

    Sn = 118.71

    3. The attempt at a solution

    Would you divide the mass of tin by 2 to get the equivalent weight of the tin?

    The equivalent weight is the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 g for oxygen.

    Pretty good, now - can you calculate what mass of oxygen did 10 g of tin reacted with?

    If so, do you know how to use proportions to calculate how much tin would react with 8 g of oxygen?
