A solution of HNO3 is standardized by reaction with pure sodium carbonate. 2H+ + Na₂CO3 → 2Na+ + H₂O + CO₂ A volume of 27.91 ± 0.05 mL of HNO3 solution was required for complete reaction with 0.9253 ± 0.0009 g of Na₂CO3, (FM 105.988 ± 0.001 g/mol). Find the molarity of the HNO3 solution and its absolute uncertainty. Note: Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations. 0.6256 0.002 [HNO3] = M ± M Incorrect Incorrect

2. Using molecular simulations it is possible to compute the free energy change AG for the nonphysical reaction CH3-CH2-CH3 CH3-CH3 (Propane Ethane) in any desired solvent. Simulation data give the following results AG°(vacuum)=0.5 kcal/mol AG (octanol)=2.0 kcal/mol AG (water) 1.0 kcal/mol (a) The experimentally measured free energy of transfer AGx(propane) of propane from octanol to water is 4 kcal/mol and from vacuum (gas phase) to water is -0.2 kcal/mol. Calculate the corresponding values of AGOx(ethane) from octanol to water and from vacuum to water. b) Assume that the free energy of transfer of a methylene group from water to octanol is a measure of the strength of the hydrophobic driving force for burial of such a group during protein folding. Calculate the expected approximate decrease in stability (as a result of reduced hydrophobicity) for a Leu Ala substitution at a buried site in a monomeric globular protein. The measured decrease in stability is twice the theoretical…
