We are being asked to find how many Liters of 0.750 M NH3 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:

M1V1=M2V2

M1 = initial concentration
V1 = initial volume
M2 = final concentration
V2 = final volume


Calculate the initial volume (milliliters needed) of the NH3 solution.
