Ascientist investigates a new substance and finds that at 35° c, 146.2 grams will dissolve in 200.0 grams of water. which similar experiment could be used to support the scientist’s results?

The scientist's results is that at a temperature of 35°C, the solubility of the substance in water is 146.2 grams in 200 grams of water. There isn't really a different method to determine the solubility of a substance in water. Another procedure could be that a lesser amount of the substance is used and the water required to dissolve it is determined. The solubility of the substance based on the two procedures can then be compared.
