Solution:
Step 1: Calculate the mass of NaOCl.
[tex]\text{percent by mass} = \frac{\text{mass of NaOCl}}{\text{mass of solution}} × 100[/tex]
[tex]\text{mass of NaOCl} = \frac{\text{percent by mass}}{100} × \text{mass of solution}[/tex]
[tex]\text{mass of NaOCl} = \frac{3.62}{100} × \text{1500.0 g}[/tex]
[tex]\text{mass of NaOCl = 54.3 g}[/tex]
Step 2: Calculate the molar mass of NaOCl.
molar mass of NaOCl = (22.99 g/mol × 1) + (16.00 g/mol × 1) + (35.45 g/mol × 1)
molar mass of NaOCl = 74.44 g/mol
Step 3: Calculate the number of moles of NaOCl.
[tex]\text{moles of NaOCl} = \frac{\text{mass of NaOCl}}{\text{molar mass of NaOCl}}[/tex]
[tex]\text{moles of NaOCl} = \frac{\text{54.3 g}}{\text{74.44 g/mol}}[/tex]
[tex]\boxed{\text{moles of NaOCl = 0.729 mol}}[/tex]
