Solution
Correct option is A)
Correct option is A)The amount of KNO3 that dissolves in 50 g of water at 40oC is closest to 100 g.
Correct option is A)The amount of KNO3 that dissolves in 50 g of water at 40oC is closest to 100 g.At 40oC, the solubility is approximately 200 g KNO3 into 100 g water.
Correct option is A)The amount of KNO3 that dissolves in 50 g of water at 40oC is closest to 100 g.At 40oC, the solubility is approximately 200 g KNO3 into 100 g water.So 50 g of water at 40oC will dissolve around 100 g of KNO3.
