Question

A solution of ammonia (NH3) contains 6.0% NH3 by volume. How many milliliters ofNH3 are in 28 mL of the solution?

Answer 1

ANSWER

The volume of ammonia in the solution is 1.68mL

EXPLANATION

Given that;

The volume of ammonia solution is 28mL

The solution of ammonia is 6% by its volume

Let represents the volume of ammonia in the solution

$\begin{gathered} \text{ The volume of NH}_3\text{ = 6\% }\times\text{ volume of the solution} \\ \text{ x = }\frac{\text{ 6}}{\text{ 100}}\text{ }\times\text{ 28} \\ \\ \text{ x = 0.06 }\times\text{ 28} \\ \text{ x = 1.68mL} \end{gathered}$

Therefore, the volume of ammonia in the solution is 1.68mL
