Solution: How many liters of 0.750 M NH3(aq) do you need to make a 0.50 L of 0.250 M NH3(aq) solution?A. 0.167 B. 0.177 C. 0.681 D. 0.125 E. 0.560


How many liters of 0.750 M NH3(aq) do you need to make a 0.50 L of 0.250 M NH3(aq) solution?

A. 0.167 

B. 0.177 

C. 0.681 

D. 0.125 

E. 0.560


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:


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

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