Question

a chemist is using 3.32 milliliters of a solution of acid and water. if 15.9% of the solution is acid, how many milliliters of acid are there? round your answer to the nearest tenth.

Explanation:

Step1: Identify the percentage and total volume

We know the total volume of the solution is 3.32 milliliters and the percentage of acid is 15.9%.

Step2: Calculate the volume of acid

We use the formula: Volume of acid = Percentage of acid×Total volume of solution. So, the volume of acid is $0.159\times3.32$.
$0.159\times3.32 = 0.52788$.

Step3: Round to the nearest tenth

Rounding 0.52788 to the nearest tenth gives 0.5.

Answer:

0.5
