Answer:

0.0705 moles NaClO

Explanation:

Assuming the bleach solution are 100mL:

First, we need to find the mass of the solution knowing density = 1.0g/mL:

100mL * (1g/mL) = 100g

Then, we must find the mass of NaClO in 100g of solution using its percentage by mass:

100g * (5.25g NaClO / 100g) = 5.25g NaClO

As the last point, we need to convert the mass to moles using molar mass of NaClO = 74.44g/mol:

5.25g NaClO * (1mol/74.44g) = 0.0705 moles NaClO
