Question

A chemist is using 366 milliliters of a solution of acid and water. If 18.9 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer 1

First, let's find the total volume of acid in the solution. Since 18.9% of the solution is acid, the volume of acid is 18.9/100 * 366 = 69.764 milliliters. We can then round this to the nearest tenth to get 69.8 milliliters.

Therefore, there are 69.8 milliliters of acid in the solution.
