calculate the molality of a commercial bleach solution that is 3.62% by mass of NaOCl in water.
commercial grade HCL solutions are typically 39.0% (by mass) HCL in water. Determine the molality and molarity of the HCL, if the solution has a density of 1.20 g/ml.
Calculate the molarity and molality of a solution that is 18.0% by mass phosphoric acid (H_3PO_4) and that has a density of 1.155 g/mL.
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 ofhousehold bleach that should be diluted with water to make 500.0 mL of a pH = 10.18 solution.
Calculate the molarity and molality of an NHz solution made up of 30.0 g of NH3 in 80.0 g of water. The density of the solution is 0.952 g/mL. Molarity = M Molality =
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.
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
