Final answer:
The scientist used 8 ounces of the solution.
Step-by-step explanation:
To find out how much solution the scientist used, we need to multiply the total amount of solution by the fraction used. The scientist used 1/6 of the 48 ounces of solution, so we can calculate:
48 ounces * (1/6) = 8 ounces
Therefore, the scientist used 8 ounces of the solution.
