How many liters of peroxide should be added to 12 liters of an 8% peroxide solution so that the resulting solution contains 16% peroxide?   original added new amount of peroxide 0.96 liters x 0.96 + x amount of solution 12 liters x 12 + x 0.18 liter 1.14 liters 1.92 liters 2.10 liters

X = 1,143 liters

Step-by-step explanation:

To solve this problem let's pose the following equation:

(Amount of peroxide added + Amount initial of Solution)*(% of desired peroxide/100) = (amount of initial peroxide + amount of peroxide added).

* The added amount is unknown and we will call it X

* The percentage of peroxide desired is 16%

* The amount of initial peroxide is calculated as follows:

(%peroxide/ 100)(amount of initial substance)

= 0.08(12)

Finally the equation is:

(X + 12)(0.16) = 0.08(12) + X

0.16X -X = 0.96 - 1.92

-0.84X = -0.96

X = 1,143

a .4y4
