Question 716996: A Chemist needs 500 milliliters of a solution that is 40% sulfuric acid, but all the she can find in the lab are solutions that are 25% sulfuric acid. How much of each should she mix?

This chemist wants a more concentrated solution of sulfuric acid than the 25% concentration reported available in the description. This chemist should have 96% or 98% sulfuric acid present, otherwise cannot make the 40% concentration which is wanted.

Does this person have maybe 50% sulfuric acid present?
x for how much 25%, y for how much 50%.
Still, there would be too much difference in densities. Volume units used for measurement? Assuming the concentrations are by volume, %w/v,
and .
Solve for x and y.
