To find out how many ounces are not peroxide in a 16-ounce bottle that contains 70% peroxide, you can use the following steps:
-
Calculate the amount of peroxide in the bottle: \[ \text{Amount of peroxide} = 70% \text{ of } 16 \text{ ounces} = 0.70 \times 16 = 11.2 \text{ ounces} \]
-
Subtract the amount of peroxide from the total volume to find out how much of the bottle is not peroxide: \[ \text{Amount not peroxide} = \text{Total volume} - \text{Amount of peroxide} = 16 - 11.2 = 4.8 \text{ ounces} \]
So, rounding to the nearest tenth, the bottle contains 4.8 ounces that are not peroxide.
