Answer 1

To find out how many ounces are not peroxide in a 16-ounce bottle that is 70% peroxide, we can first determine how much peroxide is in the bottle and then subtract that from the total volume.

1. Calculate the amount of peroxide:
\[
\text{Amount of peroxide} = 70\% \text{ of } 16 \text{ ounces} = 0.70 \times 16 = 11.2 \text{ ounces}
\]

2. Now, calculate the amount that is not peroxide:
\[
\text{Amount not peroxide} = \text{Total volume} - \text{Amount of peroxide} = 16 - 11.2 = 4.8 \text{ ounces}
\]

Therefore, the amount that is not peroxide is **4.8 ounces**.
