When 0. 36 g of nacl is dissolved in water, the resultant solution weighs 12. 80 g, with a mass percentage of NaCl=2.81%.The concentration of an element in a compound or component in a mixture can be represented.

In part by the mass percentage. It refers to how much of each element in a compound is present in mass terms. The mass percentage of nacl is computed by dividing the mass of each component by the sum of all the components and multiplying the result by 100.

The sodium ion is transformed into Hydrated when NaCl is dissolved in water. Ion-dipole interactions cause the polar water molecules and the sodium and chloride ions to be attracted to one another when sodium chloride dissolves in water.

Mass percentage of NaCl = (mass of nacl/mass of solution)*100

= (0.36/12.80)*100

=2.813%
