What is the mass percent (m/m) concentration of a solution prepared from 500. g nacl and 2.50 kg of water?

The mass percent of NaCl solution is 16.66 %

Explanation:

To calculate the mass percentage of NaCl solution, we use the equation:

Mass of solute (NaCl) = 500.0 g

Mass of solvent (water) = 2.50 kg = 2500 g    (Conversion factor: 1 kg = 1000 g)

Mass of solution = Mass of solute + Mass of solvent = 500.0 + 2500 = 3000 g

Putting values in above equation, we get:

Hence, the mass percent of NaCl solution is 16.66 %
