Sodium hypochlorite chemical name would be NaOCl. Then, the molecular weight should be:23 + 16 + 35.5 = <span>74.5 g/mole

Molarity unit is mole of molecule divided by 1000ml of solvent, in this case water. Then for 32.4g of molecule with 499ml solvent it would be:
32.4g / (74.5g/mole) / (1000ml/499ml)= 0.87 m</span>
