Question

A chemist is using 357 milliliters of a solution of acid and water. If 13.2 % of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer 1

The quantity of acid in the solution is 47.1 ml

Explanation:

Given as :

The quantity of solution of acid and water = 357 millimeters

The percentage of acid in the solution = 13.2 %

Let the quantity of acid in the solution = x ml

So, According to question

13.2 % of the total quantity of acid in the solution = x

I.e x = 13.2 % × 357

Or, x =
`(13.2)/(100)` × 357

Or, x = 0.132 × 357

∴ x = 47.124 millimeters

So , The quantity of acid = 47.1 ml

Hence The quantity of acid in the solution is 47.124 ml Answer
