Problem: Calculate the total pressure above 1.0 L of a 1.42 M CH3OH (aq) solution at 25 °C. The vapor pressure of pure methanol is 25°C at 127.1 torr and the vapor pressure of pure water is 23.8 torr at 25°C. Assume the density of the solution is 1.00 g/mL. Please explain your answer and also provide examples
