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
