Ответ:
The solubility of a substance will increases if more mass of the solvent used. It will also increase if the temperature higher. The sample is 68.4-g sample of potassium chloride in 200.0 g of water at 20°C. Then, the concentration would be
KCL mass/ H2O mass= 68.4g/200g= 34.2g/100g
The concentration is equal to solubility, so the solution is saturated
