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 (C34H32FEN.O4, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 10.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?

Q ● ENTROPY AND FREE ENERGY Calculating dG from dH and dS 4PF, (g) + 10H₂(g) P4 (s) + 20HF (g) A chemical engineer is studying the two reactions shown in the table below. In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 53.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. CH₂(g) + 20₂(g) → CO₂(g) + 2H₂O(g) ALEKS - Rafia Riaz - Learn Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then,…
