In the laboratory, a student adds 57.5 mL of water to 15.1 mL of a 0.508 M nitric acid solution. What is the concentration of the diluted solution? Assume the volumes are additive.

What is the concentration of methanol in a solution prepared by combining 7.97 mL of a 3.849 M methanol solution with 17.41 mL of water? Assume volumes are additive and report your answer to 3 significant figures.

A student has 480.0 mL of a 0.1217 M aqueous solution of LiCl to use in an experiment. He accidentally leaves the container uncovered and comes back the next week to find only a solid residue. The mass of the residue is 3.529 g. Determine the chemical formula of this residue. If the substance is a hydrate, use a period instead of a dot in its formula.

A 0.3240 g sample of potassium hydrogen phthalate is dissolved in 100.0 mL of water. If 26.79 mL of sodium hydroxide solution are required to reach the equivalence point, what is the molarity of the sodium hydroxide solution? Be sure to report your answer with the correct units and number of significant figures.

The concentration of sodium chloride in blood serum is 0.140 M. What volume of blood serum contains 6.07 g of sodium chloride?

500.0 mL of a 0.235 M solution of LiBr is diluted to 700.0 mL. What is the new concentration of the solution?

The solution was prepared by adding 150 g of sodium hydroxide to 150 g of water, giving a total weight of 300 g. Density of the solution is 1.53 g/mL What is the molarity of the solution? 2. Pause the Student Protocol video at 1 minute 39 seconds. Now use your molarity in the dilution equation to calculate the number of mL you will need to dilute to make 500 mL of a 0.10 M sodium hydroxide solution.

A diluted NaCl solution is made by mixing 110.5 mL of 1.26 M NaCl with 201.3 mL of water.  What is the final concentration of NaCl in the newly diluted solution?

You wish to make a 0.382 M hydrochloric acid solution from a stock solution of 12.0 M hydrochloric acid. How much concentrated acid must you add to obtain a total volume of 175 mL of the dilute solution?

You have 500 mL of a 0.10 M NaCl solution. You dilute the solution to a new volume of 1 L. What is the concentration, or molarity, of this diluted solution?
