Answer :
Final answer:
The concentration of NaCl at 25°C is 36.2 ppm.
Explanation:
The concentration of a solute can be expressed in parts per million (ppm), which represents the number of parts of solute per one million parts of solution. To calculate the concentration in ppm, we need to convert the solubility of NaCl into a percent concentration. The given solubility is 36.2 g/100 g solution, which means that for every 100 g of solution, 36.2 g is NaCl.
To convert this into a percent concentration, we divide the mass of NaCl by the mass of the solution and multiply by 100. So, (36.2 g / 100 g solution) * 100 = 36.2%.
Finally, we convert the percent concentration to ppm by multiplying by 10,000. Therefore, the concentration of NaCl at 25°C is 36.2 ppm.
