My chest is mixing a solution that is 2% acid and another solution that is 8% acid she needs to make 75 ml of a solution that is 5% acid how much of each solution does she use.

The answer to your question is

Volume of solution 2% = 37.5ml

Volume of solution 8% = 37.5ml

Step-by-step explanation:

Data

Solution A = 2% Volume A = ?

Solution B = 8% Volume B = ?

Final solution = 5% Final volume = 75 ml

Process

Write an equation of this experiment

       2%(Volume A) + 8%(Volume B) = 5%(75)

Volume A = x

Volume B = 75 - x

Substitution

       2%(x) + 8%(75 - x) = 375

Simplification

        2x + 600 - 8x = 375

        2x - 8x = 375 - 600

        -6x = -225

            x = -225/-6

            x = 37.5

Result

Volume A = 37.5 ml

Volume B = 75 - 37.5 = 37.5 ml

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.
