Achemistry lab needs to make 100 gallons of an 18% acid solution by mixing a 12% acid solution with a 20% solution. find the number of gallons needed of each solution.

25 gallons of 12 % acid solution and 75 gallons of 20% solution are required.

Explanation:

Let the volume of the solution 12% acid solution and 20% acid solution be x and y.

x + y  = 100 gallons...[1]

Percentage of acid solution desired to prepare = 18%

...[2]

On solving [1] and [2] we get:

y = 75 gallons , x = 25 gallons

25 gallons of 12 % acid solution and 75 gallons of 20% solution are required.
