Step 1

Number of moles for a given chemical species are defined as the ratio of mass to the molar mass. The mathematical formula which is used to calculate the number of moles is shown below:

Step 2

The molarity of a solution refers to the ratio of number of moles to the volume of the solution. Its SI units are moles/L. It is denoted by the symbol ‘M’. The formula is as shown below:

Step 3

The volume of the solution is given to be 250 mL= 0.25 L.

The mass of sodium hydroxide is given to be 4.50 g.

The molar mass ...
