Available was 250.00 ml of a 15.67 M H,S0, solution (density 1.7872 g/mL). Assume you pipetted 70.00 ml of this solution into a 500.00 mL volumetric flask, diluted it, and properly made a solution. You determined the density of this new solution to be 1.1318 g/ml. What is the molality of the new 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.

What volume of a 1.63 mass % solution of Mg(NO3)2 is needed to contain 0.316 grams of Mg(NO3)2. The solution has a density of 1.016g/mL.

at a certain temperature,1.85 grams of barium hydroxide will dissolve to form 100.0 ml of a saturated barium hydroxide solution. the molar mass barium hydroxide is 171.34 grams/mole. what is the concentration of the solution in unit molarity? what is the constitution of the hydroxide ion in the same solution?

5.00 g of solid Al(NO3)3 was added to enough water to make a solution with a total volume of 100.0 mL.  Al(NO3)3 is very soluble in water and this much solid will fully dissolve in a 100.0 mL solution.  If 65 mL of water was added to the original 100.0 mL Al(NO3)3 solution described to the left in order to dilute the solution.  Calculate the new diluted solution concentration, in Molarity? Assume the volumes of the 2 solutions are additive.

A given solution is prepared by pouring 23.998 g NaOH into 200.0 mL water. (use correct number of significant digits in each case) What is the molarity of the solution? What is the normality of the solution? What is he molality of the solution?

44.0 mL of water was added to 100.0 mL of 0.250 M CaCl₂ solution. Assume the volumes are additive. Determine the CaCl₂ concentration in the diluted solution.

You dissolve 29.22 g of NaCl in 250 mL of water. You then dilute the solution to a new volume of 1,000 mL. What is the new concentration of the diluted solution?

You dissolve 9.9 mmol of sodium bicarbonate into a total volume of 4.31 mL. What is the molarity of sodium bicarbonate in the resulting solution. (Give your answer in units of M, with two places after the decimal point.)

A 122-mL sample of a 1.2 M sucrose solution is diluted to 500.0 mL. What is the molarity of the diluted solution?
