How many gallons of pure orange pulp must be added to 30 gallons of a 20% solution of orange pulp to make it a 50% solution?


Is there an easy and quick formula for this type of questions?

M1V1=M2V2 I believe it should work with this one.

M1V1=M2V2 I believe it should work with this one.

It has to be modified a little in this case, but the idea is basically the same.

(0.2)(30) + (1.0)(X) = (0.5)(30+X)

Your M1V1 term is the sum of the components you're mixing.
