    3. The attempt at a solution
    I'm unsure of what to do for this problem. I can't seem to find the ratio of whole numbers that would work for this problem. Since i know that element x are the same masses

    If compound A would be XY with the given masses, how much Y would you need to make XY2 with 1 gram of X?
