Explanation:

The percent by mass of sodium chloride (NaCl) : 7.692%

Further explanation

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

So the concentration of a solution can be expressed as a percent which is the ratio of solute to solution. Can be expressed in percent of mass (m / m) or volume percent (v / v)

Solution = Solute + Solvent

The solute is the substance that is dissolved usually in smaller amounts when compared to solvents

dissolving 125 g of sodium chloride(NaCl) in 1.5 kg of water (H₂O)

solute = = 125 g

solvent = water = 1.5 kg = 1500 g

Solution = Solute + Solvent

Solution = 125 + 1500 = 1625 grams

Then the mass percentage of sodium chloride :
