Solution Concentration
Concentration is expressed more importantly as molarity (M).
Molarity (M) = Moles solute / Liter Solution
An important relationship is M x Vsolution= mol
This relationship can be used directly in mass calculations of chemical reactions.
What is the molarity of a solution of 1.00 g KCl in 75.0 mL of solution?
M KCl = [1.00g KCl / 75.0mL ][1molKCl / 74.55 g KCl ][ 1000mL / L]
