An aqueous solution of acetone is made by transfering 38.1 mL of liquid acetone to a 500. mL volumetric flask, and then adding enough water to fill the flask to the mark. What is the volume/volume percentage of acetone in the 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.

An aqueous Nal solution is prepared by dissolving 23.95 g Nal in enough water to produce 175.7 mL of solution. What is the molarity of this solution?

If 0.069 mol of salicylic acid was added to 62.92 mL of pentanol, what would be the concentration of the resulting solution in units of g solute/100 g solvent? MW of salicylic acid= 138.12 g/mol MW of pentanol= 88.15 g/mol Density of pentanol= 0.8144 g/mL

Glucose (molar mass=180.16 g/mol) is a simple, soluble sugar. Glucose solutions are used to treat patients with low blood sugar. Suppose you prepare a glucose solution using the described procedure. • Step 1: Dissolve 240.6 g of glucose in enough water to make 500.0 mL of solution. • Step 2: Transfer 18.6 mL of the solution to a new flask and add enough water to make 250.0 mL of dilute solution. What is the concentration (in M) of the glucose solution at the end of the procedure?

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?

Suppose 9,07 g of potassium acetate is dissolved in 50. ml. of a 0.70 M aqueous solution of sodium chromate Calculate the final molarity of potassium cation in the solution. You can assume the volume of the solution doesn't change when the potassium acetate is dissolved in it. Round your answer to 2 significant digits.

You have 1g of lithium orotate with a molar mass of 163.03. You wish to make 100ml of 5mM lithium orotate in aqueous solution. How many grams of lithium orotate would you need?

imagine that a 2.0 m colution of copper 2 chloride is added to a piece of aluminum.  draw a particulate representation of the mixture after any reaction has completed

A chemistry student must write down in her lab notebook the concentration of a solution of sodium thiosulfate. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 6.0 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 94.86 g. • She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 122.28 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. 1 [1] 8.mL-¹ x10 X Ś
