An aqueous solution of sodium nitrate, NaNO3 , is made by dissolving 26.7 grams of sodium nitrate in sufficient water in a 300. mL volumetric flask, and then adding enough water to fill the flask to the mark. What is the weight/volume percentage of sodium nitrate in the solution? Weight/volume percentage = %

Calculate the molarity (to at least three significant digits) of a solution created when 108 mL of a 1.3-M NaCl solution is added to 100. mL of a 2.2-M NaCl solution.

The density of sodium chloride is 2.164 g cm-³. What is the molar concentration of NaCl in a 14.5 cm³ sample of pure NaCl? molar concentration = i M What is the molar concentration of NaCl in a 25.9 g sample of pure NaCl? molar concentration = M

The mass percentage of hydrochloric acid within a solution is 36.00%. Given that the density of this solution is 1.179 g/mL, find the molarity of the solution. molarity of HCl solution= M

A 0.3120 g sample of potassium hydrogen phthalate is dissolved in 100.0 mL of water. If 25.60 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.

Calculate the molarity of a solution made by adding 54.1 g of NaNO3 to a flask and dissolving with water to a total volume of 3.00 L . Express the concentration to three significant figures and include the appropriate units. HẢ ? molarity = Value Units

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.

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

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?

Suppose 8.29 g of sodium bromide is dissolved in 200. ml. of a 0.50 M aqueous solution of potassium carbonate. Calculate the final molarity of bromide anion in the solution. You can assume the volume of the solution doesn't change when the sodium bromide is dissolved in it. Round your answer to 3 significant digits.
