Unformatted text preview: Concentation Concentation W Units of concentration mass % (w/w) volume % (v/v) molar concentration Molarity Molarity W The most common unit of concentration is molarity (M). W It is defined as the number of moles of solute per liter of solution. ) ( ) ( L solution of volume solute moles M Molarity = Example Example W A solution is made by dissolving 0.180g of glucose in enough water to make 100mL. What is the concentration of this solution? mol mol g g MM m n 3 10 00 . 1 / . 180 180 . = = = mM L mol V n M 10 100 . 10 00 . 1 3 = = = How to use molarity How to use molarity W mass and volume, calculate molarity W molarity and volume, calculate moles (or mass) W mass and molarity, calculate volume Chapter 4 Chapter 4 Chemical Reactions in Aqueous Solutions Types of solutions Types of solutions W Conductance of solutions Strong electrolytes readily conduct electricity Weak electrolyte conduct electricity weakly Non-electrolytes dont conduct electricity at all Strong electrolytes...
