The molarity of the solution is 2.05 mol/kg, it can be expressed in terms of kilograms as well as liters.
Molarity is defined as the number of moles of the solute to the volume of the solution in liters or weight of solution in kilograms.
It is expressed as follows:
M= n/V or M=n/W
Molar mass of NaCl = 58.4 g/mol
Given mass of NaCl=12 g
The weight of the solution=100 g
Molarity can be calculated as follows:
M= 12/58.4*0.1
M=2.05 mol/kg
The molarity of the solution is 2.05 mol/kg.
