48.80 g is the mass % of nacl in the solution .

What are the three methods for determining the concentration of a solution?

Moodiness (M): The volume of solution and the number of moles (n) of the solute are used to compute it (V).

Fraction of a mole (x): It is the proportion between the number of moles of a specific element and the overall number of moles of the substance ( ).

How do you figure out mass?

A body's mass is constant at all times. One formula to determine mass is mass = volume density. The gravitational force exerted on a mass is measured by its weight. Kilogram is the term for the SI unit of mass.

Mass of solute (sodium chloride) = 36 g

Mass of solvent (water) = 12. 80g

Mass of solution = Mass of solute + Mass of solvent

= 36 g + 12. 80g = 48.80 g
