The solubility of sodium chloride, NaCl is 36g/100g of H2O at 20 degrees C. Indicate whether the resulting solutions of sodium chloride in water are saturated, unsaturated, or supersaturated.
a) A stock room technician dissolves 5.8 g of NaCl in 100 ml of water at 20 degrees C. for a conductivity test solution.

b) 48.0 g of NaCl are mixed with 116.7 g of water, nut does not dissolve completely.

c) At 40 degrees C. 20.0g of NaCl is dissolved in 50.0 g water then cooled back down to 20 degrees C. with the salt remaining in solution.

Please explain. Thank you!
