A chemistry student wants to determine the percentage of ethanol in a sample of wine. The student takes a 50 mL aliquot of the wine, dries it, and finds the weight of the residual solids to be 0.325 g. The student then distills the rest of the wine, evaporates the distillate to dryness, and finds the weight of the residue to be 2.324 g. Using mass balance calculations, what is the percentage of ethanol in the wine sample?

A chemistry student is studying the adsorption of a gas on a solid surface using the Langmuir adsorption isotherm. The student knows that the maximum adsorption capacity (θ_max) of the surface is 0.5 mol/L and that the equilibrium constant (K) for the process is 0.02 L/mol. The student is asked to calculate the fraction of the surface covered by the adsorbate when the gas pressure is 2 atm at the temperature of the experiment.
