The molarity of sodium hypochlorite in bleach should be calculated. Concept introduction: The number of moles of a substance is related to mass and molar mass as follows: n = m M Here, m is mass and M is molar mass of the substance. Also, according to Avogadro’s law in 1 mol of a substance there are 6.023 × 10 23 units of that substance. Here, 6.023 × 10 23 is known as Avogadro’s number and denoted by symbol N A . The molarity of a solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows: M = n V Here, n is number of moles of solute and V is volume of solution in L. Thus, the unit of molarity is mol/L.

Interpretation Introduction
Interpretation:
The molarity of sodium hypochlorite in bleach should be calculated.
Concept introduction:
The number of moles of a substance is related to mass and molar mass as follows:
n=mM
Here, m is mass and M is molar mass of the substance.
Also, according to Avogadro’s law in 1 mol of a substance there are 6.023×1023 units of that substance. Here, 6.023×1023 is known as Avogadro’s number and denoted by symbol NA.
The molarity of a solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows:
M=nV
Here, n is number of moles of solute and V is volume of solution in L. Thus, the unit of molarity is mol/L.
