Homework Statement
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?
Homework Equations
The Attempt at a Solution
the first solution .4*200=80
the second .7*150=105
80+105=350x
x=52.9%wt methanol
amount is 150+200=350g
