Interpretation Introduction

Interpretation: The volume required for KI extraction sample is to be calculated.

Concept Introduction:

Molarity of a substance is defined as the number of moles of solute dissolved per liter of solution.

The relation between molarity (M), volume and number of moles of a solute is:

M=moles soluteL solution

A number of moles are equal to the ratio of the mass of substance and molecular mass of a substance.

The relation between mass (m) and molar mass is:

n=mMolar Mass

need help please and thanks dont understand only need help with C-F Learning Goal: As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7). Part A - Difference in binding free eenergies Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol. The margin of error is 2%. Part B - Compare difference in free energy to the thermal…
