You need to find the molarity of NaOCl in a 3.2 % mass bleach solution. What else do you need to know to find the molarity? How would you find the value experimentally?
We need to find the value of the density of the bleach solution in order to calculate the value of molarity
Now consider the solution of 1000 mL
Mass of solution = 1000d
Percent of NaOCl = 3.2/100 * 1000d = 32d
Calculate the number of moles of NaOCl, that will be equal to molarity

Liquid bleach is an aqueous solution of sodium hypochlorite (NaOCl). This brand has a concentration of 5.8% NaOCl by mass. What is it’s molarity? Assume the density of bleach is the same as that of water.
Calculate the molarity and molality of a commercial bleach solution that is 8.62% by mass of NaOCl in water and has a density of 1.10 g/mL.
calculate the molality of a commercial bleach solution that is 3.62% by mass of NaOCl in water.
A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume of household bleach that should be diluted with water to make 500.0 mL of a pH = 10.18 solution. Use the Ka of hypochlorous acid found in the chempendix
A 3.00-mL bleach (NaOCl is the active ingredient) sample is mixed with potassium iodide and acid to completely form triiodide (I3 - ) ions. You then titrate the I3 − ions with a thiosulfate (S2O3 2− ) solution you have previously determined to be 0.1306 M. The endpoint is reached when 31.52 mL of the thiosulfate solution is added. What is the molar concentration of the bleach solution? What is its mass percent?
Ordinary household bleach is an aqueous solution of sodium hypochlorite. What is the molarity of a bleach solution that contains 37.0 g of sodium hypochlorite in a total volume of 2.70 x 10² mL?
The label on a bleach bottle states that it contains 5.25 percent (by mass) sodium hypochlrite (NaOCl). Assume that the bleach is manufactured by adding this chemical to otherwise pure water. Take the density of bleach to be the same as that of pure water, 1.0 g cm-3. Assume that NaOCl dissociates completely. (a) what is the pH of bleach? (b) Bleach can be used as an emergency disinfectant-for example, for water after an earthquake. Assume that the target does...
You have 1500.0 g of a bleach solution. The percent by mass of the solute sodium hypochlorite (NaOCI) is 3.62%. How many grams of NaCl are in the solution?
a solution contains 3.2 g NaOH (mw = 40) in 20.0 ml of solution. what is the molarity of the solution?
Household chlorine bleach is a water solution that is 5.00% by mass sodium hypochlorite. What is the molality of the hypochlorite in the solution? What is the mole fraction of hypochlorite in the solution?
