Based on the following data, determine the molecular weight of the unknown solute. Note the "initial freezing point" refers to the freezing point of the solvent as a pure substance while the "final freezing point" refers to the freezing point of the mixture. Mass Solvent: 15.000 g FPD Constant of Solvent: 4.9 Mass Solute 2.350 g Initial Freezing Point: 85.3oC Final Freezing Point: 82.4oC Your answer should follow the format: a) ΔT b) Molality of the Solution c) mols of solute d) Molecular weight of Solute
(Q74) At what temperature (in °C) will a solution in which 88.37 grams of iron (III) chloride has been added to 1,054 grams of water boil? The boiling point of water is 100.00°C. You should use the experimental value of the van't Hoff factor for this calculation. (5 sf)
Consider a 250mL solution composed of 25% pentane by volume and 75%n-pentanol by volume. The following is a summary of the chemical and physical data for these two organic compounds. Pentane (CsH,12): bp = 36.1°C, MW = 72.15 g/mol, p = 0.626 g/mL n-Pentanol (CsH1,OH): bp = 138.5°C, MW = 88.15 g/mol, p = 0.814 g/mL %3D a) Can the components of the pentane/n- pentanol solution described above be effectively separated by simple distillation? No. A simple distillation cannot effectively separate these two components because simple distillations are only capable of separating liquid mixture when at least one of the components is water. No. A simple distillation cannot effectively separate these two components because their molecular weights are too similar Yes. A simple distillation can effectively separate these two components because their boiling points are sufficiently different. Yes. A simple distillation can effectively separate these two components because their densities are…
