of 29.0.) 3.13. A liquid mixture is prepared by combining N different liquids with densities 1,2N. The volume of component i added to the mixture is Vi and the mass fraction of this component in the mixture is xi. The components are completely miscible. Determine which of the following two formulas should be used to estimate the density of the liquid mixture, , if the volume of the mixture equals the sum of the pure-component yolumes, 5 =i=1Nxii(A)1=i=1Nixi Determine whether (A) or (B) is the correct formula (show your proof), and then use the correct formula to estimate the density (g/cm3) of a liquid mixture containing 60.0wt% acetone, 25.0wt% acetic acid, and 15.0 w\% carbon tetrachloride. 3.14. A gas chromatograph (GC) is a device used to separate the components of a sample of a gas or liquid mixture and to provide a measure of the amount of each component in the sample. The output from a
