The solubility of sodium chloride is about 0.36 g per gram of water at 25 degrees Celsius. g (2 dec places) of NaCl will dissolve in 96 g of water at 25 degrees Celsius. If there were 43.92 g of NaCl dissolved in 122 g of water, the solution would be (unsaturated/saturated/supersaturat ed).

Saturated.

Explanation:

Hello,

In this case, we understand that solubility accounts for the maximum amount of a solute to completely dissolve into a solvent, in such a way, sodium chloride's solubility at 25 °C is 0.36 g of NaCl per gram of water, thus, if a relationship is greater than this value, the solution will be supersaturated, if it is equal saturated and if is less it will be unsaturated. In such a way, for 43.92 g of sodium chloride and 122 g of water, the relationship result:

Thus, such solution would be saturated as the relationship equals the solubility.

Best regards.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
