    1. The problem statement, all variables and given/known data
    Two methanol-water mixtures are contained in separate flasks. The first mixture contains 40wt% methanol and the second contains 70wt% methanol. If 200g of the first mixture is combined with 150g of the second, what are the mass and composition of the product?

    2. Relevant equations

    3. The attempt at a solution
    the first solution .4*200=80
    the second .7*150=105
    x=52.9%wt methanol
    amount is 150+200=350g
