Question

Consider the solubilities of a particular solute at two different temperatures. Temperature (°C) 20.0 30.0 Solubility (g/100 g H,0) 45.5 79.2 Suppose a saturated solution of this solute was made using 82.0 g H,O at 20.0 °C. How much more solute can be added if the temperature is increased to 30.0°C? mass

Answer 1

Sol set the Comparing it at 20g solute how problem cep as if you are latios: 100g of H₂O can hold 45.2 g of much can sag of water hold? (, е 45.28 = (Rg 1009 829 x= 82x45.2 Too x= 37.064g then do same for at 30 c. 79.29 100g = (x)9 828 xa 82 x 19.2 100 as 64.944 g you should get & equal to 37. sugat 20c & 64.944g at 30 c. then find difference between these amounts and you have your answer of how much more solute can be added. 64.944 - 37.064 = 27.889
