Question

a 4% peroxide solution is mixed with a 10% peroxide solution, resulting in 100 l of an 8% solution. the table shows the amount of each solution used in the mixture.
peroxide solution

	liters of solution	peroxide concentration	total
10% peroxide	s	0.10	y
mixture	100	0.08	z

what is the value of z in the table?
8
7
6
9

Explanation:

Step1: Recall the formula for mixture problems

The total amount of peroxide in the mixture is the sum of the peroxide from each solution. The formula for the amount of peroxide is \( \text{Liters of Solution} \times \text{Peroxide Concentration} \). For the mixture, we can calculate \( z \) by multiplying the total liters of the mixture (100 L) by the concentration of the mixture (0.08).

Step2: Calculate \( z \)

Using the formula \( z = 100\times0.08 \)
\( z = 8 \)

Answer:

8
