Step 1

The number of moles for a given compound or a molecule refers to the ratio of its mass to the molecular mass. The mathematical relationship is as follows:

Step 2

The molarity of the given chemical solution is related to the number of moles of the solute and the volume of the solution (in liters) as follows:

Step 3

The pH of a given solution can be termed as a measure of its basicity or acidity. It is a measure of the concentration of the hydrogen or the hydronium ions which are present in the given solution. More the pH of a given solution, more will be its basicity, and lesser the pH of a given solution, more will be its acidity.
