Vilka [71]

Answer:

The quantity of acid in the solution is 47.1 ml

Step-by-step 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

<u>So, According to question </u>

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

I.e x = 13.2 % × 357

Or, x = \frac{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
