How many ml of cranberry juice is required to prepare a 10 ml 16% cranberry solution using a 20% cranberry stock solution?

8 mL of cranberry juice is required to prepare a 10 mL 16% cranberry solution using a 20% cranberry stock solution.

Explanation:

Let the volume of the 20% cranberry stock solution be x

Volume of cranberry juice in x volume = 20% of x = 0.2 x

Desired volume of 16% cranberry solution = 10 mL

Volume of cranberry juice in 10 mL = 16% of 10 =

Volume of cranberry juice in x volume = Volume of cranberry juice in 10 mL

0.2 x = 1.6 mL

x = 8 mL

8 mL of cranberry juice is required to prepare a 10 mL 16% cranberry solution using a 20% cranberry stock solution.
