Answer : The correct option is, (a) molarity × liters of solution
Explanation :
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used for molarity is :
[tex]\text{Molarity}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}[/tex]
or,
[tex]\text{Moles of solute}=\text{Molarity}\times \text{Volume of solution (in L)}}[/tex]
Thus, the correct option is, (a) molarity × liters of solution
To obtain the number of moles of solute, the operation that we have to use is molarity x liters of solution.
The term molarity or concentration refers to the number of moles of a solute in one liter of the solvent. This is the reason why the unit of concentration is moles per liter.
Hence, to obtain the number of moles of solute, the operation that we have to use is molarity x liters of solution.
