A constant pressure "coffee-cup" calorimeter is used to measure the heat of reaction between 0.10 L of 1.0 M NaOH and 0.10 L of 1.0 M HCI. Both solutions initially are at 24.0°C; after the solutions are mixed, the final temperature is 30.4°C. If the heat capacity of the resulting solution is assumed to be totally due to water (Cp = 75.291 J/mol•K), how much heat was evolved from the reaction per mole of limiting reactant? Assume the density of all solutions is 1.0 g/mL. (C = 75.291 J/mol•K for H20; q = CcalAT) 270 kJ/mol 5.4 kJ/mol 22 kJ/mol 123 kJ/mol 54 kJ/mol

You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C₃₄H₃₂FeN₄O₄, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 34.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample? -don't prematureley round
