The solubility of NaCl sodium chloride in water at 25C is approximately 357 g/L.To find the maximum amount of NaCl that can be dissolved in 500 mL of water, we can use the following equation:Amount of NaCl g = Solubility g/L Volume L First, we need to convert the volume from mL to L:500 mL = 0.5 LNow, we can calculate the maximum amount of NaCl that can be dissolved:Amount of NaCl g = 357 g/L 0.5 L = 178.5 gSo, the maximum amount of NaCl that can be dissolved in 500 mL of water at 25C is approximately 178.5 grams.
