Determine which is/are the solvent and the solute from the following bicarbonate buffer solution components: 1.00 g of sodium bicarbonate, 9.00 g of sodium carbonate, and 1.0 kg of water.

Determine whether the following describes a suspension, colloid, or solution: some particles of blood plasma cannot pass through semipermeable membranes. 

Identify the pair/s that will form solutions.
i. CoCl₂ and water
ii. Octane (C₈H₁₈) and water
iii. Toluene (C₆H₅CH₃) and CCl₄

One way to express a concentration of a solution is by using volume/volume percent concentration. Define volume/volume percent concentration and determine the type of solutions in which it is used.

Hydrochloric acid is used to neutralize the ammonia produced from a Kjeldahl method where all nitrogen organic substances are converted to ammonia. In a 4.37 g sample of organic material, 23.0 mL of 0.280 M HCl (aq) was used up. Determine the mass percentage of nitrogen in the sample.

NH₃(aq) + HCl(aq) → NH₄Cl(aq)

A solution is prepared by dissolving 11.00 grams of benzoic acid (molar mass = 122.12 g/mol) in 211 grams of water. It has a density of 1.26 g/mL.

a. Calculate the % mass of the solution

b. Calculate the molarity of the solution

c. Calculate the molality of the solution

What is the mass/volume percent (m/v) of the solute MgCl₂ if a 50.0 mL sample of MgCl₂ solution contains 8.00 grams of MgCl₂?

Calculate the concentration (in % m/v) of a 120.0 mL solution containing 0.129 mol glucose (C₆H₁₂O₆).

Provide the steps in preparing 250.0 mL of a 1.5% (m/v) NaOH solution.

In a chemical laboratory, a task was assigned to analyze the molarity of picric acid (C₆H₃N₃O₇) solution, a Hager's reagent for detecting alkaloids. In an empty evaporating dish weighing 29.5 g, a 20.0 mL sample of C₆H₃N₃O₇ solution is placed. The total mass of the evaporating dish containing the C₆H₃N₃O₇ solution is 49.7 grams. The C₆H₃N₃O₇ solution placed in the evaporating dish is dried in an oven. After drying, a total mass of 29.7 grams is obtained for the evaporating dish and the anhydrous C₆H₃N₃O₇. Determine the molarity of the C₆H₃N₃O₇ solution.

If 20.0 g of NaOH has been weighed out, what is the volume (in milliliters) of 12.5% (m/v) solution that can be prepared? How many milliliters of 0.225 M NaOH solution can be prepared from the same mass of NaOH?

What is the molarity of a nitric acid solution that was prepared by mixing 75.00 mL of 0.150 M HNO₃ and 125.00 mL of 0.250 M HNO₃?
