Ethylene dibromide ($C_2H_4Br_2$) and 1,2-dibromo propane ($C_3H_6Br_2$) form a series of ideal solution over the whole range of composition. At 85$^{\large\circ}$C, the vapour pressures of these pure liquids are 173 mm Hg and 127 mm Hg respectively.If 10g of ethylene dibromide is dissolved in 80g of 1, 2-dibromo propane. Calculate the partial pressures of each components and the total pressure of the solution at 85$^{\large\circ}$C.

1 Answer

20.42mm Hg
