We are told that the concentration of sodium hypochlorite is 4.0% (w/v). To calculate the molarity of the sodium hypochlorite solution, let us consider a sample volume of 0.1 liter. Since we are given a w/v (Percent of weight of solution in the total volume of solution) value, it means that there are 4 <span>grams of sodium hypochlorite per 100 mL of solution (0.1 liter). Molarity is measured in moles per liter. So we'll just convert the given 4 grams to moles using the molar mass.

4 grams</span>sodium hypochlorite * (1 mol sodium hypochlorite/ 74.44 g sodium hypochlorite) = 0.054 moles sodium hypochlorite
So we have 0.054 moles sodium hypochlorite / 0.1 L solution

Thus the molarity is 0.53 mol/L or just 0.53 M.

Yes, this is a balanced chemical equation, and it obeys the Law of Conservation of Mass.
A balanced chemical equation obeys the Law of Conservation of Mass if there are the <em>same numbers of each type of atom on each side of the reaction arro</em>w.
2H₂ + O₂ ⟶ 2H₂O
Let’s check the numbers.
<u>Atom</u> <u>On the left</u> <u>On the right</u><u>
</u>
H 4 4
O 2 2
We have the same numbers of H and O atoms on each side of the reaction arrow.
The equation is<em> </em>balanced and it obeys the Law of Conservation of Mass.
