a. Calculate the molarity of the undiluted bleach solution. b. Commercial bleaches such as Clorox are said to contain 5.25%NaOCl by weight. Is this correct? Use your results and a density of 1.0 g/mL for the bleach in your calculations. These calculations should reflect the precision of the assumed density.
