if 20 g of sodium chloride are dissolved in 100 cm3 of water at 20gC, is the solution saturated?

yeah because i say so
To determine whether the solution is saturated, we need to compare the actual concentration of the solution with its solubility at the given temperature.
The solubility of sodium chloride (NaCl) in water can vary with temperature. At 20°C, the solubility of NaCl is approximately 36 grams per 100 milliliters of water.
In this case, we have 20 grams of NaCl dissolved in 100 cm3 (which is equivalent to 100 milliliters) of water at 20°C. Therefore, we can compare the actual concentration (20 g/100 mL) with the solubility (36 g/100 mL) at this temperature.
Comparing the actual concentration with the solubility:
20 g/100 mL < 36 g/100 mL
Since the actual concentration is less than the solubility, we can conclude that the solution is not saturated.
