1. What mass of solute will dissolve in 100 g of water at the following
temperatures?
a. Xat 55°C =
b. Y at 15°C =
c. Z at 43°C=

faster? Is there any possibility of separating mixture of X, Y and Z?
3. What is the solubility of X, Y and Z at 40°C? What can you conclude from
this observation?
4. At 20°C, 47 g of 'X' is dissolved in 100 g of water. Is this solution saturated
or unsaturated? How do we know?
