2. In attempting to calculate the density of chloroform, CHCl3, Riley determines the following densities: 1.30 g/mL, 1.35 g/mL, 1.32 g/mL, 1.23 g/mL, 1.13 g/mL, and 1.39 g/mL. a. Calculate the average density of chloroform from his data. b. If the accepted density of chloroform is 1.48 g/mL, calculate the percent error. C. Was Riley's data accurate? Was the data precise? Explain your reasoning. Experiment 1: Determination of the Density of Water and nft page 14 3. For each of...
A polymer of large molar mass is dissolved in the organic solvent chloroform (CHCl3) at 25 °C, and the resulting solution rises to a final height of 7.99 cm above the level of the pure solvent, as solvent molecules pass through a semipermeable membrane into the solution. If the solution contains 3.97 g polymer per liter, calculate the molar mass of the polymer. Take the density of the solution to be 1.48 g cm-3.
Your lab partner combined chloroform (CHCl3) and acetone (C3H60) to create a solution where the mole fraction of chloroform, Xchloroform, is 0.219. The densities of chloroform and acetone are 1.48 g/mL and 0.791 g/mL, respectively. Calculate the molarity of the solution. Number Calculate the molality of the solution. Number Imi ITI

1) Will Chloroform (CHCl3; density = 1.489 g/cm3) form the lower layer? True False 2)The compounds 2.3-dimethylbutane and 2-methylpentane are structural isomers geometrical isomers functional isomers diastereoisomers
The nonvolatile, nonelectrolyte aspirin, C9H8O4 (180.1 g/mol), is soluble in chloroform, CHCl3. Calculate the osmotic pressure generated when 12.0 grams of aspirin are dissolved in 179 ml of a chloroform solution at 298 K. The molarity of the sollution is? The osmotic pressure of the solution is?
The vapor pressure of chloroform is 173.1 mm Hg at 25 °C. How many grams of estrogen (estradiol), C18H24O2, a nonvolatile, nonelectrolyte (MW = 272.4 g/mol), must be added to 171.0 grams of chloroform to reduce the vapor pressure to 170.7 mm Hg ? chloroform = CHCl3 = 119.40 g/mol. g estrogen How many grams of estrogen?
14. The Density of Chloroform-1.4832g/ml, Nitroglycerin= 1.6g/ml, water= 0.9982 and Toluene- 0.8669. If Maurice, Mckoy and Aaron shake these liquids in a beaker (assuming there is no reaction) and allows the liquids to settle, they would expect to see: A) Water to be at the top and Chloroform at the bottom of the beaker B) Nitroglycerin at the bottom and Toluene at the top C) Water at the bottom and Toluene at the top D)Nitroglycerin at the top and Toluene...
The vapor pressure of chloroform is 173.11 mm Hg at 25°C. How many grams of testosterone, C19H28O2, a nonvolatile, nonelectrolyte (MW = 288.4 g/mol), must be added to 299.3 grams of chloroform to reduce the vapor pressure to 171.03 mm Hg ? chloroform = CHCl3 = 119.40 g/mol. _______ g testosterone
