How many grams of KNO3 would recrystallize from 100 g of water, if a saturated solution were cooled from 50 degrees celcius to 2
Lelechka [254]

Answer:

m_{cryst}=58g

Explanation:

Hello there!

In this case, according to the attached solubility chart, it is possible for us to realize that about 88 grams of KNO3 are soluble at 50 °C but just 30 grams are soluble at 20 °C in the same 100 g of water.

In such a way, the crystalized mass of this solute can be calculated by subtracting the mass at 50 °C and the mass at 20 °C:

m_{cryst}=88g-30g\\\\m_{cryst}=58g

Best regards!
