a. 100 g of NaNO; dissolved in 100 g of water at 30°C
b. 30 g of KCIO; dissolved in 50 g of water at 50°C
c. 90 g of KNO dissolved in 100 g of water at 60°C
d. 110 g of KCI dissolved in 200 g of water at 80°C
e. What mass in grams of KNO; are needed to prepare a saturated solution in 100 g of water at 50°C?
a. NaNO3 is soluble in water, so it will dissolve completely in 100 g of water at 30°C.
b. KCIO3 is soluble in water, so it will dissolve completely in 50 g of water at 50°C.
c. KNO3 is soluble in water, so it will dissolve completely in 100 g of water at 60°C.
d. KCl is soluble in water, so it will dissolve completely in 200 g of water at 80°C.
e. The solubility of KNO3 in water at 50°C is 38.8 g/100 g of water. Therefore, to prepare a saturated solution in 100 g of water at 50°C, you would need 38.8 g of KNO3.
