approximately 1.143 L of peroxide should be added to the original solution. 

Answer:

Step-by-step explanation:

Alright, lets get started.

We have solution of 12 liters which has 8% peroxide solution.

Suppose we add x liters of peroxide in it.

It means mixture will be (x+12) liters.

This mixture should have 16 % of peroxide.

It means

[tex](x+12)*\frac{16}{100}=(12*\frac{8}{100}) +x[/tex]

[tex](x+12)*0.16=(12*0.08) + x[/tex]

[tex]0.16x+1.92=0.96+x[/tex]

[tex]x-0.16x=1.92-0.96[/tex]

[tex]0.84x=0.96[/tex]

[tex]x=\frac{0.96}{0.84}=1.143[/tex]

So the answer is 1.143.

1.143 liters peroxide should be added.   :    Answer
