Q4/ A liquid mixture is prepared by combining N different liquids with densities pi; pz: ... PN. The volume of component i added to the mixture is V, and the mass fraction of this component in the mixture is x. The components are completely miscible. The following two formulas provide estimates of the density of the liquid mixture, , if the volume of the mixture equals the sum of the pure-component volumes. Only one of the formulas is correct, however. (i) p (ii) Determine whether (i) or (i) is the correct formula (show your proof), and then use the correct formula to estimate the density (g/cm) of a liquid mixture containing 60.0 wt% acetone, 25.0 wt% acetic acid, and 15.0 wt% carbon tetrachloride.

Archimedes tells us the lifting power of a balloon (how much mass it can lift) is equal to the difference between the mass of the balloon and the mass of the air it displaces. That is, if the balloon occupies the same volume as 10 kg of air, but the balloon only weighs 2 kg, then the balloon can lift 8 kg. Content Airships have sometimes been filled with hydrogen (H₂), but hydrogen is very flammable, and after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead.

A mixture of ethanol (ethyl alcohol) and water contains 40.0% water by mass.(a) Assuming volume additivity of the components, estimate the specific gravity of themixture at 20°C. What volume (in liters) of this mixture is required to provide 150 mol ofethanol?(b) Repeat Part (a) with the additional information that the specific gravity of the mixture at20°C is 0.89045 (making it unnecessary to assume volume additivity). What percentage errorresults from the volume-additivity assumption?
The principal reaction in a series of complex reactions performed by microorganisms involved in wine making is the conversion of sugars into alcohol in a process known as fermentation. The starting concentration of sugars determines the final alcohol content and the sweetness of the wine. Adjusting the specific gravity of the stock solution achieves the desired quality of the wine. Assuming the sugars in the stock solution with a specific gravity of 1.075 are all C12H22011 equivalent to 12.75% wt., calculate the following:a) How much is the amount of sugar per kg of water?b) How many lbs of solution is present in a cubic feet of solution?c) What is the weight of sugar in grams for every liter of solution?
