Question

How many ounces of a 4% acid solution and how many ounces of a 10% acid solution must be mixed to make 24oz of a 6% acid solution

Answer 1

a = acid solution 4%

b = acid solution 10%

a + b = 24

0.04*a+0.1*b=0.06*24

a=24-b

0.04*(24-b) + 0.1*b = 1.44

0.96 - 0.04b + 0.1*b = 1.44

0.06*b = 0.48

b = 8 oz

a=24-b

a = 24 - 8
