Question
The liquid-vapour equilibrium diagram of the binary water (H2O)-nitric acid (HNO3) under standard pressure
is shown in the appendix. The mass fraction of HNO3 is plotted on the x-axis and the temperature on the y-
axis.
The analysis of a sample of the mixture obtained during the industrial preparation of nitric acid gives a total
mass for this sample of 80 g and a mass of 60 g of water.
