Titus was dissolving his analyte and produceda colloidal type of precipitated. It indicates that: His sample undergoes a slow reaction with an increasing relative supersaturation. The relative supersaturation is small. His sample undergoes slow reaction nucleation. The relative supersaturation is large.

Why is Tyndall effect shown by colloidal particles? State four instances of observing the Tyndall effect.

A biochemical engineer isolates a bacterial gene fragment and dissolves a 11.5-mg sample in enough water to make 30.0 mL. of solution. The osmotic pressure of the solution is 0.340 torr at 25.0 "C. Assume the gene fragment does not dissociate into multiple ions when added to the solution. Be sure each of your answer entries has the correct number of significant figures. Note: Reference the Conversion factors for non-SI units table for additional information. Note: Reference the fundamental constants table for additional information. Note: Reference the Molal freezing point depression and boiling point elevation constants table for additional information. Part 1 of 2 What is the molar mass of the gene fragment? mal Part 2 of 2 0.8 If the solution density is 0.997 how large is the freezing point depression for this solution? ml. 'C D.P G ala 14 E

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

a solutipn prepared by dissolving 6.95 x 10^-3 g of protein in 0.0300L of water has an osmotic pressure of .195 torr at 25 degrees C. Assuming the protein is noneletrolyte,determine the molar mass of the gene fragment
