Question

A chemist is using 326 milliliters of a solution of acid and water. If 18.3% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer 1

We have a 326 ml of a solution with 18.3% of acid.

We have to calculate the amount of acid there is.

We can find it as the volume of the solution, 326 ml, times the proportion of acid, 18.3/100 = 0.183:

$326\cdot0.183=59.658\approx59.7$

Answer: there are 59.7 ml of acid.
