The conversion of nitrogen to ammonia, an essential process in the nitrogen cycle, occurs only in the presence of an iron-molybdenum cofactor. The concentration of molybdenum in one such co-factor was determined by titration with an acidified permanganate solution. The titration reaction equation is 4H*(aq) + 3MnO (aq) + 5Mo³+ (aq) → 3Mn²+ (aq) + 5M002+ (aq) + 2H₂O(1) A 30 mL sample of Mo³(aq) required 21.8 mL of 0.10 mol/L permanganate solution to reach a light pink end point. From the titration data, the concentration of Mo³+ (aq) is determined to be Record your answer to 2 sig-digs; do not include units. mol/L.

The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.

The iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion.
