Answer :
Final answer:
Mixing equal volumes of hydrogen peroxide and saline results in a 50% strength solution, assuming volumes are additive.
Explanation:
When 8 fl oz of hydrogen peroxide is mixed with 8 fl oz of saline, a solution with 50% strength is created. This percentage is derived from calculating the volume ratio of hydrogen peroxide in the whole solution. Specifically, the volume of hydrogen peroxide divided by the total volume gives you the strength of the solution (8 oz / (8 oz + 8 oz) = 0.5 or 50%). However, this interpretation assumes that the volumes are additive, which might not be the case for all solutions.
