What mass of ammonium chloride can be added to 100 g of water at 20 degrees C before the solution becomes saturated?

look at your solubility table (grams/100gH2O vs temp for varous compounds)
Yours ought to be more readable than this

can you tell me what to write
To determine the mass of ammonium chloride that can be added to 100 g of water at 20 degrees C before the solution becomes saturated, we need to know the solubility of ammonium chloride at that temperature.
The solubility of a substance is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature. In this case, we need to find the solubility of ammonium chloride in water at 20 degrees C.
One way to find the solubility is to refer to a solubility table or a handbook that provides such information. These resources often list the solubility of different substances at various temperatures. Alternatively, you can perform an internet search for the solubility of ammonium chloride at 20 degrees C.
Once you have the solubility of ammonium chloride at 20 degrees C, you can compare it to the amount of water (100 g) and find the mass of ammonium chloride that can be added before saturation.
Remember, if you exceed the solubility limit, the excess ammonium chloride will not dissolve and will form a solid precipitate at the bottom of the container.
