Chemistry - Liquid Solution Question with Solution | TestHub

On mixing, heptane and octane form an ideal solution. At $373\mathrm{K}$, the vapour pressures of the two liquid components (heptane and octane) are $105\mathrm{kPa}$ and $45\mathrm{kPa}$ respectively. Vapour pressure of the solution obtained by mixing $25.0\mathrm{g}$ of heptane and $35\mathrm{g}$ of octane will be (molar mass of heptane $=100\mathrm{g}{\mathrm{mol}}^{-1}$ an dof octane $=114\mathrm{g}{\mathrm{mol}}^{-1}$ ).
