उत्तर
Solubility is the maximum amount of solute in grams – that will saturate 100 g of water at 0°C.
Or
Maximum amount of solute that can be dissolved in 100 g of solvent at specific temperature.
No, 10 g is not solubility as the solution is unsaturated and not saturated solution. This means more of solute can be added to make it saturated solution.
