See your post above.

To calculate [ClO^-] in a 6% bleach solution, we need to consider the concentration of NaClO and the density of the solution.

First, let's calculate the concentration of NaClO in the solution:

1. Determine the mass of NaClO in 100 grams of bleach:
We know that the bleach solution contains 6 grams of NaClO per 100 grams of bleach. So, the mass of NaClO in the solution is 6 grams.

2. Convert the mass of NaClO to moles:
The molar mass of NaClO is 22.99 g/mol (Na) + 35.45 g/mol (Cl) + 16.00 g/mol (O) = 74.44 g/mol. To convert grams to moles, divide the mass by the molar mass:
Moles of NaClO = 6 g / 74.44 g/mol = 0.0805 mol

3. Determine the volume of the solution:
The density of the 6% bleach solution is given as 1.07 g/mL. This means that for every 1 mL of solution, there are 1.07 grams of bleach.
Since the solution's concentration is given in terms of 100 grams of bleach, we can say that the volume of the solution is 100 mL.

4. Calculate the concentration of NaClO in the solution:
Concentration (in Molarity) = Moles / Volume (in liters)
Convert the volume from mL to L: 100 mL = 100 mL / 1000 = 0.1 L
Concentration of NaClO = 0.0805 mol / 0.1 L = 0.805 M

Therefore, the concentration of ClO^- in the 6% bleach solution is 0.805 M.
