Answer #1

The molarity is the concentration of a substance and it is calculated by dividing the number of moles of the solute with the volume of the solution in litres. It can be expressed as shown below:

Calculate the molarity as shown below:

Therefore, "1.63M" is the correct answer.

Hence, the option (a) is correct.
