Concentration of Solutions and Molarity
www.dentonisd.orgMaking Dilutions –Diluting a solution reduces the number of moles of solute per unit volume, but the total number of moles of solute in solution does not change. •The total number of moles of solute remains unchanged upon dilution, so you can write this equation. •M 1 and V 1 are the molarity and volume of the initial solution, and M 2 and V
