Strategy:
 The boiling point of a liquid is the temperature at which its vapour pressure becomes equal to the atmospheric pressure (standardly 760 mm Hg or 1 atm).

Step 1: Read the graph
Identify the curve representing the pure solvent (usually the upper curve, as it has a higher vapour pressure than the solution at any given temperature).

Step 2: Find the intersection
Locate the point on the solvent curve where the vapour pressure is 760 mm Hg (1 atm).
