Question

A chemist is using 331 milliliters of a solution of acid and water. If 13.7% of the solution is acid, how many mA chemist is using 331 milliliters of a solution of acid and water. If 13.7% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.illiliters of acid are there? Round your answer to the nearest tenth.

Answer 1

To determine the milliliters of acid in the solution, multiply the total volume (331 mL) by the percentage of acid (13.7%), and then round to the nearest tenth to get 45.3 milliliters of acid.

Step-by-step explanation:

The chemist is using 331 milliliters of a solution of acid and water, where 13.7% of the solution is acid. To find the amount of acid in milliliters, you multiply the total volume of the solution by the percentage of the acid. Therefore, the calculation would be:

331 mL × 0.137 = 45.347 mL of acid

After rounding to the nearest tenth, the chemist has 45.3 milliliters of acid in the solution.
