+clear 

+clc

+

+//INPUT

+per_ethanol=60;//mole percent of ethanol in a ethanol-water system

+per_water=40;//mole percent of water in a ethanol-water system

+v1=57.5*10^-6;//partial molar volume of ethanol in the ethanol-water system in m^3

+rho=849.4;//density of the mixture in kg/m^3

+M_ethanol=46*10^-3;//molar mass of ethanol in kg/mol

+M_water=18*10^-3;//molar mass of ethanol in kg/mol

+

+//CALCULATION

+X1=per_ethanol/100;//calculation of the mole fraction of ethanol (no unit)

+X2=per_water/100;//calculation of the mole fraction of water (no unit)

+M=(X1*M_ethanol)+(X2*M_water);//calculation of the molar mass of the ethanol-water mixture in kg/mol

+v=M/rho;//calculation of the molar volume of the mixture in m^3/mol

+v2=(v-(X1*v1))/(X2);//calculation of the partial molar volume of water using Eq.(9.10) in m^3/mol

+

+//OUTPUT

+mprintf("\n The partial molar volume of water = %f m^3/mol\n",v2);
