Final answer:

The mass percent (m/m) of NaCl in the solution is 24.52% by dividing the mass of NaCl by the total mass of the solution and then multiplying by 100.

Step-by-step explanation:

To calculate the mass percent (m/m) of a solution, you divide the mass of the solute by the total mass of the solution and then multiply the result by 100. In this case, the mass of sodium chloride (NaCl) is 57.24 g and the mass of water (H2O) is 176.1 g. The total mass of the solution will be the sum of the mass of NaCl and H2O, which is 57.24 g + 176.1 g = 233.34 g.

The mass percent of NaCl is calculated as follows:

(Mass of NaCl / Total mass of solution) x 100%

(57.24 g / 233.34 g) x 100% = 24.52%

Therefore, the mass/mass percent concentration of the NaCl solution is 24.52%.

To calculate the mass percent of a solution, we need to divide the mass of the solute by the mass of the solution and multiply by 100. In this case, the mass of NaCl is 57.24 g and the mass of H₂O is 176.1 g. So, the mass percent of NaCl in the solution is (57.24 g / (57.24 g + 176.1 g)) * 100 = 24.5%.
