Excess molar volumes and excess Gibbs energies in N-methylformamide+water, or +methanol, or +ethanol at the temperature 303.15K

Excess volumes V-E measured in a dilution dilatometer and total vapor pressures at the temperature 303.15 K are reported for (N-methylformamide + water), (N-methylformamide + methanol), and (N-methylformamide + ethanol) over the entire composition range. The total vapor pressure measurements were made by a modified static method. The excess molar volumes are negative for all, the mixtures over the entire composition range; the vapor pressure measurements show only small negative deviations from ideality for these systems.
