At a certain temperature, when 100 g of A solution is evaporated off 20 g of water and 4 g of crystal is precipitated at a constant temperature, if 10 g of water is evaporated off and 3 g of crystal is precipitated, what is the solubility at this temperature? At a certain temperature, when 100 g of A solution is evaporated off 20 g of water and 4 g of crystal is precipitated at a constant temperature, if another 10 g of water is evaporated off and 3 g of crystal is precipitated, what is the solubility at this temperature?
20 G of water is evaporated and 4 g of crystal is precipitated knowing that it is saturated at this time
If 10 g of water is evaporated again,3 g of crystal is precipitated and 10 g of water dissolves 3 g of crystal
Solubility is 3/10=0.3
