Question

Now suppose, instead, that 16.412 g of a volatile solute is dissolved in 440.0 g of water. This solute also does not react with water nor dissociate in solution. The pure solute displays, at 20°C, a vapour pressure of 1.754 torr. Again, assume an ideal solution. If, at 20°C the vapour pressure of this solution is also 17.413 torr. Calculate the molar mass of this volatile solute.
