Solubility describes the amount of a substance that can be dissolved in another substance. This measurement can range from nearly completely insoluble under any conditions, such as oil and water, to near infinitely soluble, such as ethanol and water. The process of dissolving should not be confuse...
- Molality of the solution, m=1.0molal 2. Calculate Moles of Solute and Solvent: - For a 1.0 molal solution, we have 1 mole of solute in 1 kg (1000 g) of solvent (water). - Molar mass of water (H₂O) = 18 g/mol. - Moles of solvent (water) = 1000g18g/mol≈55.56mol....
