The laundry bleach is listed at 5.25% m/m NaClO. Calculate the concentration of the NaClO in the laundry bleach solution in mol/L. Assume the density of the bleach solution is of 1.05 g/L.

Solutions

Expert Solution

Let us assume that volume of the laundry bleach is 1L

since , desity = mass/volume and volume is 1 L

so, mass of laundry bleach will be 1.05 gm

Mass % of NaClO = mass of NaClO *100 /TOTAL MASS

5.25 = mass of NaClO*100/1.05

mass of NaClO = 0.055125 gm

Molar mass of NaClO = 74.5 gm

Number of moles of NaClO = mass/ molar mass

                                       = 0.055125 / 74.5

                                       = 7.4*10-4 mol

Volume = 1 L (assumed earlier)

Concentration of NaClO = number of moles / volume

                                   = 7.4*10-4 mol /1L

                                   = 7.4*10-4 mol/L

Answer: 7.4*10-4 mol/L
