← Hexane, 86 g/mol, and heptane, 100 g/mol, form an ideal solution. Take their vapour pressures at 298 K as 20 kPa and 6 kPa. A solution is made from 129 g of hexane and 350 g of heptane. What is the total vapour pressure above it?308 g of carbon tetrachloride, molar mass 154 g/mol, holds 16.0 g of a non-volatile solute of molar mass 64 g/mol. Pure carbon tetrachloride has a vapour pressure of 15.3 kPa at 298 K. What is the vapour pressure of the solution? →
