To find out how many ounces are not peroxide in the 16-ounce bottle that is 70% peroxide, we can first figure out how much of the bottle is peroxide and then subtract that from the total volume.
- Calculate the amount of peroxide:
\[ \text{Amount of peroxide} = 0.70 \times 16 \text{ ounces} = 11.2 \text{ ounces} \]
- Now, calculate the amount that is not peroxide:
\[ \text{Amount that is not peroxide} = 16 \text{ ounces} - 11.2 \text{ ounces} = 4.8 \text{ ounces} \]
Therefore, the amount of the solution that is not peroxide is 4.8 ounces.
