Sample problem of molarity

WebMolarity liters of solution This is probably easiest to explain with examples. Example #1:Suppose we had 1.00 mole of sucrose (its mass is about 342.3 grams) and proceeded to mix it into some water. It would dissolve and make sugar water. We keep adding water, dissolving and stirring until all the solid was gone. Weband 2.500 liters of water, the overall molarity of your solution is 2.67 M. 5) This problem is also solved in the same way as #3 and #4. Because you have 1.51 x 10-4 moles of Pb(C 2 H 3 O 2) 4, and 0.0035 L of water, the total concentration is 4.32 x 10-2 M, or 0.0432 M. 6) The equation for molarity states that the molarity of a solution is ...
