3 Ex. 1What is the molarity of a solution that was prepared by dissolving 11.5g of solid sodium hydroxide in 1.50L of water?
4 Ex. 2Calculate the molarity of a solution prepared by dissolving 1.56g of gaseous HCl in enough water to make mL of solution.
5 ExamplesCalculate the number of moles of chloride ions in 1.75L of M zinc chloride.Typical blood serum is about 0.14M NaCl. What volume of blood contains 1.0mg of NaCl?To analyze the alcohol content of a certain wine, a chemist needs 1.00 L of an aqueous 2.5 M potassium dichromate solution. How much solid must be weighed out to make this solution?
6 DilutionWhen water is added to a concentrated solution in order to achieve the desired molarity(molarity)(volume) = (molarity)(volume)
7 Ex.What volume of 16M sulfuric acid must be used to prepare 1.5L of a .10 M solution?
