A beauty supply company has 53 liters of 5% hydrogen peroxide solution on hand. The company also has a nearly limitless amount of a solution that contains 35% hydrogen peroxide. How many liters of the 35% hydrogen peroxide solution should the company add to the 5% hydrogen peroxide solution to obtain a mixture of 11% hydrogen peroxide?

Correct answer:

V2 =  13.25 l

Step-by-step explanation:

V1=53 l q1=5%=1005=201=0.05  q2=35%=10035=207=0.35 q=11%=10011=0.11  V1 q1+V2 q2=q (V1+V2) 53 0.05+V2 0.35=0.11 (53+V2)  0.24V2=3.18  V2=0.243.18=13.25  V2=453=13.25=13.25 l
