moles before dilution = moles after dilution. From the definition of molarity, we know that the moles of solute equals the molarity times the volume. So we can substitute MV (molarity times volume) into the above equation, like this: M. 1 V 1 = M 2 V 2 The "sub one" refers to the situation before dilution and the "sub two" refers to after dilution.

Dilution (equation) - Wikipedia
• Molarity is the # moles solute per liter of solution. • The symbol [ ] is used to denote molarity of a substance. Dilution: When you dilute a solution, you can use this equation: Example: Describe how you would prepare 2.50 L of 0.665 Na 2 SO 4 solution starting with:

Dilution: Definition and Calculations
Since the solute amount stays constant allows us to develop an equation for calculation. moles before dilution = moles after dilution. From the definition of molarity, we know that the moles of solute equals the molarity times the volume o mol solute = V x M. By substituting MV (molarity times volume) into the above equation, we get: MiVi = MfVf

Molarity - Quia
What molarity would the potassium nitrate solution need to be if you were to use only 2.5 L of it? Using a 4.0 M solution of MgSO4 , determine how to make 300 mL of a 1.7 M dilution. If you dilute 174 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution.
