what mass of ammonium chloride can be added to 100g of water at 20 degrees C before the solution becomes saturated
The solubility of a solute (ammonium chloride) in a solvent (water) is the maximum mass of the solute that can dissolve in 100 ml. of solvent at the given temperature.
The solubility of ammonium chloride in water at 20 degrees C is 37.2 g. according to Wikipedia, under ammonium chloride.
so what do i write as the answer
Look at the answer PC gave you. He defines saturated solution AND tells you the solubility of NH4Cl. What else is there to know?
Unfortunately this is not the intended answer.
Could you please show how you got 411 grams?
