Question

I need some help, due in an hour

A chemistry student wants to obtain 18 mL of a 53% salt solution. He currently has a 50% salt solution and a 60% salt solution on hand. How much of each solution will need to be mixed together to yield 18 mL of a 53% salt solution?

Answer 1

Explanation:

Let x be the amount of 50% salt solution and y be the amount of 60% salt solution.

We can set up the following equation:

x + y = 18

0.5x + 0.6y = 0.53(18)

Solving for x and y yields:

x = 9.6 mL of 50% solution

y = 8.4 mL of 60% solution
