We are being asked to find how many Liters of 0.750 M NH_{3} is needed to make a 0.50 L of 0.250 M solution.

When we are **adding water (or solvent) to a solution** to decrease its concentration, we are **diluting **the solution.

When dealing with **dilution **we will use the following equation:

$\overline{){{\mathbf{M}}}_{{\mathbf{1}}}{{\mathbf{V}}}_{{\mathbf{1}}}{\mathbf{=}}{{\mathbf{M}}}_{{\mathbf{2}}}{{\mathbf{V}}}_{{\mathbf{2}}}}$

M_{1} = initial concentration

V_{1} = initial volume

M_{2} = final concentration

V_{2} = final volume

**Calculate the ****initial volume (milliliters needed) of the NH _{3} solution.**

How many liters of 0.750 M NH_{3}(aq) do you need to make a 0.50 L of 0.250 M NH_{3}(aq) solution?

A. 0.167

B. 0.177

C. 0.681

D. 0.125

E. 0.560
