Question

Pragya tested the solubility of three different substances different temperatures and collected the data as given bel (results are given in the following table, as grams of substan dissolved in 100 grams of water to form a saturated solutie Substance Dissolved Temperature in K 283 293 313 333 Solubility 351 an Potassium nitrate 21 32 62 106 167 Sodium chloride 36 36 36 37 37 Potassium chloride 35 35 40 46 tó 5 Ammonium chloride 24 37 41 55 66 (a) What mass of potassium nitrate would be needed produce a saturated solution of potassium nitrate​

Answer 1

Answer:

Nevertheless, the Fraser River still remains the world's greatest single river producer of Pacific salmon. Trend analyses for escapements over recent decades show statistically significant increases for all Pacific salmon escapements combined and for pink, chum, chinook, and sockeye individually.

Answer 2

Answer:

100 g of water contains potassium nitrate = 62 g 50 g of water contains potassium nitrate = 62/100 X 50 = 31g

Thus, 31 g potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 g of water at 313 K.

Hope it helped..!
