Calculate the molarity of the commercial bleach before it was diluted. bleach 6.25%

1 answer

6.25%. Is that w/w or w/v? (I have two bottles at home; both say 6.50% but neither specifies w/w or w/v.) Assuming w/v, it means 6.25g NaClO/100 mL soln.
6.25/molar mass NaClO = moles NaClO.
That x 10 will be moles in 1000 mL which will be the molarity.
