The solubility of potassium chloride in water at 60 * s is equal to 50 g. Determine the mass fraction of salt in a solution saturated at the indicated temperature.
Given:
t = 60
P = 50 g.
w% -?
Decision:
1) 50 grams of salt dissolves in 100 grams of water, therefore the mass of the solution is 100 + 50 = 150 g.
2) w% = 50/150 * 100 = 33.3%
Answer: 33.3%
