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...
2. The density of iron at 910 °C is 7.571 g/cm3 for the a-form and 7.633 g/cm3 for the y-form. The heat absorbed in the α-γ transition is 912 J/mole. (Note that I cm2 atm. = 0.1013 J.) Disregarding the dependency of change in volume with pressure, what is the change in molar volume of iron (in cm/mole)? Calculate the equilibrium temperature for this transformation at a pressure of 1000 atm a. b.

1-) Silica gel has a bulk density of about 0.3 g/cm3, so 15 g would occupy a volume of 45-50 cm3 (45-50 mL). This quantity is called the: 2-) You are carrying out a chromatographic separation on a 15 mg sample using 6.5 g of silica gel in your column. If you aim for a column height of 10 cm of silica gel, what is the inside diameter of the necessary chromatography column in units of cm? 3-) Consider the...
