Achemist dissolved crystals of an unknown substance into water at room temperature. he found that 33 g of the substance can be dissolved into 100 ml of water. what property of the unknown substance was the chemist most likely investigating?

This chemist was most likely investigating the solubility of the substance. Solubility is the chemical property that refers the maximum amount of solute that can be dissolved in a certain amount of solvent at a given temperature and pressure. Here the 33 g of the unknown substance is the solute and the 100 ml of water is the solvent. The solubility is expressed as 33 g / 100 g of water.
