Q 3. Pragya tested the solubility of three different substances at different temperatures and collected the data as given below (results are given in the following table, as grams of a substance dissolved in 100 grams of water to form a saturated solution).
(a) What mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313 K?
Mass of potassium nitrate = 62g in 100 g of water
Therefore, according to question,
Mass of potassium nitrate in 50 g of water at 313K
