Question

vapour pressure of a solution of heptane & octane is given by the equation: P(sol.)(mm Hg) = 35 + 65x, where x is the mole fraction of heptane. Calculate the vapour pressure of pure octane.7

Answer 1

Answer:

35 , if only octane is present then mole fraction of heptane would be zero and the vapour pressure would correspond to pure octane
