Densities were measured for the binary mixtures of methanol, ethanol, 1-propanol, 1-butanol with nitromethane at temperatures (293.15, 298.15, 303.15 and 308.15) K and for 1-pentanol with nitromethane at temperatures (303.15 and 308.15) K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Excess molar volumes as a function of mole fraction were derived, and the computed results were fitted to the Redlich–Kister equation. Excess molar volumes of mixtures studied were consistently described by the ERAS model. Also The Peng–Robinson–Stryjek–Vera (PRSV) equation of state was applied, in combination with simple mixing rules
