You need to find a graph of solubility in your textbook. It should have temperature on the x-axis and "grams dissolved per 100 grams H2O" on the y-axis (or some such.) Sodium nitrate is less soluble in cool water than warm. Use the graph to determine how many grams are dissolved at 50°C, multiplying by 2 since there are 200 grams H2O. Then determine how many grams are dissolved at 20°C, again multiplying by 2. Subtract the two numbers to find the grams that will precipitate

How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
Start by looking up atomic masses of Na, N and O. Convert grams to kilograms.
You need 145,337 g silver nitrate.
Solubility of Ammonium Nitrate at room temperature( 25 degree celsius) is 160-170 grams per 100 ml of water. Its solubility increases as temperature rises. Ammonium Nitrate is a ionic substance with high hydration enthalpy n low lattice energy. So, it dissolves giving Ammonium cations and Nitrate anions in water.

1 mole of Na2SO4 is 142.05 or 142.1 when using 4 significant figures
Solubility of NaNO3 is 1.25 kg/kgwater. There are solubility vs temperature curve of many sodium salt available in the internet and text book.
The answer is 14,35 g AgCl.
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.
