How do you calculate percent of sodium hypochlorite NaClO?

Answer 1

Weight x.xx g dry NaClO and add it to about 90 mL water, dissolve completely and fill up till 100 mL exactly: then you've got a x.xx g/100 mL solution. (This is almost x.xx %).

If you want it more exactly: add the same amount to 100-x.xx GRAMs of water. (Now it is almost 100 mL).

Answer 2

To calculate the percentage of sodium hypochlorite (NaClO) in a solution, divide the mass of NaClO by the total mass of the solution, then multiply by 100 to get the percentage. The formula is: (mass of NaClO / total mass of solution) x 100 = percentage of NaClO.
