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

Explain how you would prepare a saturated solution of sugar in water?
No. If a saturated solution is heated, it will no longer be fully saturated. Water at 25°C will be saturated with sugar at a ratio of 100 grams of sugar to 100 grams of water. At 50°C it would take 130 grams of sugar to reach saturation. See this link for a full explanation: http://www.scienceclarified.com/Ro-Sp/Solution.html
