Combustion of a fuel sample in a bomb calorimeter increases the temperature of the entire system by 5.10 °C if the calorimeter contains 1700 g of water, but only by 4.00 °C if the calorimeter contains 2200 g of water. What is the heat capacity of the dry bomb calorimeter assembly? Assume that the specific heat capacity of water is 4.18 J g–1 °C–1.

Plot a line weaver-burk graph for Km=6.30mM and Vmax=360uM/min when an experiment has 5 tubes with concentrations of substrates of 1.0mM, 10mM, 50mM, and 100mM.

Carbon monoxide gas is dissolved in water at 25 \deg C and 0.065 atm. If the constant for this system is 5.80 x 104 M/atm, what is the solubility of CO? Answer the number to the wholest number

Solution A is 20 degrees celsius, Solution B is 80 degrees celsius (both are the same kind of solution). The goal is to make a 50 degree celsius solution; How much of solution A do you need (starting with 100g of solution B)? (cp=4.184 J/g C)

Four lab groups completed the experiment listed in the lab diluting lul of FCF dye into 1ml of water. The A625 values are listed below. For brilliant blue FCF, ɛ =97000 M-1cm–1 MW = 792.8 g/mol %3D Group # A625 % solution (in original stock sample) Percent ror (True value of Stock=0.2%) 1 0.244 0.199 0.5 0.209 0.170 15 3 0.306 0.250 25 4 0.187 0.153 0.235 a. Which group was more accurate? b. What are possible reasons group 3 had a much higher Absorbance than the others? c. What are possible reasons group 4 had a much lower Absorbance than the others?

A solution is made by dissolving 0.641 mol of nonelectrolyte solute in 763 g of benzene. Calculate the freezing point, T;, and boiling point, Tp, of the solution. Constants can be found in the table of colligative constants. %3D °C Tp = °C
