Answer #1

6.25%w/V sodium hypochlorite solution means 6.25 g of sodium hypochlorite presence in 100ml of solution

100ml of solution contains 6.25 g of sodium hypochlorite

15ml of solution contains = 6.25*15/100 = 0.9375g sodium hypochlorite

no of moles of sodium hypochlorite   = W/G.M.Wt

                                                           = 0.9375/74.44 = 0.0126 moles
