Question

How many liters of peroxide should be added to 12 liters of an 8% peroxide solution so that the resulting solution contains 16% peroxide

Answer 1

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

Answer 2

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

$(x+12)*\frac{16}{100}=(12*\frac{8}{100}) +x$

$(x+12)*0.16=(12*0.08) + x$

$0.16x+1.92=0.96+x$

$x-0.16x=1.92-0.96$

$0.84x=0.96$

$x=\frac{0.96}{0.84}=1.143$

So the answer is 1.143.

1.143 liters peroxide should be added.   :    Answer
