Step 1

The number of moles for a given chemical species refers to the ratio of mass of the species to that of its molar mass. The formula is shown below:

Step 2

The molarity or the concentration can be defined as the ratio of number of moles of solute which are present per liter of the given solution. The SI units of molarity are moles/L. The mathematical formula as follows:

Step 3

The molarity as well as the volume of an unknown solution during the titr...
