mols C2H5OH = grams/molar mass. Use density to convert mL to grams.
mols H2O = grams/molar mass. Use density to convert mL to grams.
Then XC2H5OH = nC2H5OH/total mols
XH2O = nH2O/total mols
pH2O = XH2O x P<sup>o</sup><sub>H2O,/sub>
pC2H5OH = XC2H5OH x P<sup>o</sup><sub>C2H5OH</sub>
Ptotal = pC2H5OH + pH2O
