Question

A chemist is using 351 milliliters of a solution of acid and water. If 14.1% of the solution is acid, how many milliliters of acid are there

Answer 1

49.491 millimeters of acid is present

Solution:

Given that, chemist is using 351 milliliters of a solution of acid and water

14.1% of the solution is acid

To find: Milliliters of acid present

From given statement,

Solution of acid and water = 351 ml

14.1% of the solution is acid, which means that 14.1 % of 351 ml is acid

Therefore,

Milliliters of acid present = 14.1 % of 351 ml

Here "of" means multiplication

Therefore,

`\text{ Milliliters of acid present } = 14.1 \% * 351`

`\rightarrow 14.1 \% * 351\\\\\rightarrow (14.1)/(100) * 351\\\\\rightarrow 0.141 * 351 = 49.491`

Thus 49.491 millimeters of acid is present
