explanation:
to understand this solution first we should know the definition for boiling point.
boiling point : the temperature at which liquid vapor pressure is equal to gas atmospheric pressure is called boiling point.
normal atm pressure = 760 torr or 1 atm
just draw a line we get the value temperature 64oC
