A 10-liter cylinder, closed with a piston and placed in a thermostat at a temperature of 40 °C, contains 0.05 mol of two substances. Determine the mass of liquid in the cylinder after isothermal compression, as a result of which the volume under the piston decreases by 3 times. At a temperature of 40 °C, the saturated vapor pressure of the first liquid is pн1 = 7 kPa, the saturated vapor pressure of the second liquid at the same temperature is pн2 = 17 kPa. Draw a compression isotherm. The molar mass of the first liquid is M1=1.8•10-2 kg/mol, and the second - M1=4.6•102 kg/mol.
