READ THE FOLLOWING PASSAGE AND ANSWER THE
FOLLOWING QUESTIONS:
A solution is a homogeneous mixture of two or more
substances. At any particular temperature, a solution that has
dissolved as much solute as it is capable of dissolving is said to
be saturated solution. The amount of solute contained in the
saturated solution at this temperature is called its solubility. If
the amount of solute contained in a solution is less than the
saturation level, it is called as unsaturated solution. The
concentration of solution is the amount of solute present in a
given amount of solution. The concentration of a solution can be
expressed in two methods. Mass by mass percentage of a
solution and Mass by volume percentage of a solution.

mixture?
a) Air
