A 66.7 mL sample of 18.0 M sulfuric acid was diluted with enough water in a volumetric flask to make 5.00 x 102 mL of solution. A 25.0 ml aliquot of this solution was then further diluted to a volume of 1.50 x 102 ml. What is the molarity of the solution after the second dilution?

A sample of 8.27 g8.27 g of solid calcium hydroxide is added to 34.5 mL34.5 mL of 0.480 M0.480 M aqueous hydrochloric acid. Write the balanced chemical equation for the reaction. Physical states are optional. What is the limiting reactant?     How many grams of salt are formed after the reaction is complete? mass of salt:   How many grams of the excess reactant remain after the reaction is complete?

In the laboratory you dilute 3.30 mL of a concentrated 3.00 M perchloric acid solution to a total volume of 175 mL. What is the concentration of the dilute solution?

Suppose 6.22 g of ammonium iodide is dissolved in 250. mL of a 0.20 M aqueous solution of potassium carbonate. Calculate the final molarity of iodide anion in the solution. You can assume the volume of the solution doesn't change when the ammonium iodide is dissolved in it. Be sure your answer has the correct number of significant digits.

An 8.00 mL sample of a stock solution of sodium acetate is diluted with enough water to form 100.0 mL of 3.0 x 10-4 M NaC2H3O2. What is the molarity of the original stock solution?

A chemist places 2.2352 g of NaCl in a 100 mL volumetric flask and adds water to the mark and calls this stock solution 1. The student then pipets 21 mL of the stock solution 1 into a 50 mL volumetric flask and adds water to the mark and mixes to make solution 2. Then the pipets 15 mL of solution 2 into a 70 mL volumetric flask and dilutes to the mark to make solution 3. Determine the molar concentration of sodium sulfate in solution 3 prepared.

A solution of NaCl is prepared by dissolving 1.75 g NaCl in enough water to make 100.00 mL of solution. A 10.00 mL aliquot of the solution is then taken and dissolved to a final volume of 1000.00 mL.  What is the final solution concentration in molarity?

In the laboratory you dilute 4.49 mL of a concentrated 6.00 M nitric acid solution to a total volume of 100 mL. What is the concentration of the dilute solution?
