Final answer:
The bottle contains 11.2 ounces of peroxide, so there are 4.8 ounces of non-peroxide.
Step-by-step explanation:
To determine how many ounces of the bottle are not peroxide, we need to calculate the amount of peroxide in the bottle first. The bottle is labeled as 70% peroxide, which means that 70% of the total volume is peroxide. In this case, the bottle contains 16 ounces, so the amount of peroxide is 0.70 x 16 = 11.2 ounces. To find the amount of non-peroxide, we subtract the amount of peroxide from the total volume: 16 - 11.2 = 4.8 ounces.
