Question

How solubility of a sloution is calculated?

Answer 1

Solubility is measured either in grams per 100 g of solvent – g/100 g – or number of moles per 1 L of the solution. As an example, calculate the solubility of sodium nitrate, NaNO3, if 21.9 g of the salt is dissolved in 25 g of water. Based on this calculation, the final volume of the NaNO3 saturated solution is 55 ml. Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated.

Answer 2

Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of thecompound by the mass of the solvent and then multiply by 100 g to calculatethe solubility in g/100g .
