At
, the vapour pressure of a solution containing
mole of
-hexane and
moles of
-heptane is
of
. At the same temperature, if one more mole of
-heptane is added to this solution, the vapour pressure of the solution increases by
of
. What is the vapour pressure in
of
-heptane in its pure state
Text Solution
Verified by ExpertsThe correct answer is:
600
