If all of the hydrogen in NaHCO3 was evolved as H2O vapor, how many moles of H20 were formed in your experiment? How does this number of moles (of H2O) compare to the number of moles of NaHCO, you initially measured. Mass of NaHCO3 - 3.002g NaHCO3 Molar mass - 84.0056g/mmog Moles - 0.0357moles Rxns original decomp equation used in experiment: NaHCO3(s) + heat —> CO2 + H2O(g) + Na2CO3 (s)
Power Index = 178% Heat of explosion (Qv) = 6666kJ/kg Gaseous products detected: CO2, H2O, and N2 (no other gases detected) Total moles of gaseous products detected: 5.3 moles You must determine the molar mass of this compound and draw a reasonable Lewis structure for it. (Hypothetical)

The molecular weight of hemoglobin is 64,500 daltons (= g mol-1). A. How much oxygen can be bound per g of hemoglobin? Express the values as mL per g of hemoglobin, where mL is the volume of O2. R =0.082 L atm mol-1 oK-1, oK =273 + oC. The molar volume of O2 is given as V = nRT/P where P = 1 atm and n= 1 mol. (Hint: 1.0 mol x 0.082 L atm mol-1 oK-1 x 273.2 oK / 1 atm = 22.4 L mol-1) (Hint: The number of moles of O2 that can be bound per g of hemoglobin is 4 x the moles of Hb in 1 g). B. The blood in a person contains 15 g of hemoglobin per 100 ml blood. How much oxygen does the blood contain at 95 mm Hg if hemoglobin is 98% saturated and the solubility of O2 is 0.003 mL dL-1 mmHg-1? (Hint: Total O2 content = HbO2 + free dissolved O2) C. Suppose the venous PO2 is 40 mm Hg, and that hemoglobin is 75% saturated at this point. What is the oxygen content of venous blood? D. Suppose the cardiac output is 5 L min-1. Calculate the oxygen delivery to the tissues from B and C. (Hint: Rate of…
