Question

 A chemist has a 30% and a 45% acid solution. What amount of each solution should be used to make 500ml of solution with 35% acidity?

A)133 1/3 ml of 30% solution and 366 2/3 ml of 45% solutionB)250 ml of each solutionC)333 1/3 ml 30% solution and 166 2/3 ml of 45% solutionD)400 ml of 30% solution and 100 ml of 45% solution

​

Answer 1

The correct answer is:

C. 333 1/3 ml 30% solution and 166 2/3 ml of 45% solution.

If a chemist has a 30% and a 45% acid solution and wants to make a 500ml solution with 35% acidity it has to be like the statement above describes.
