The mass of HNO 3 that is present per liter of solution is to be calculated. Concept introduction: Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release H + ions and OH − ions. Weak acids and weak bases are the substance that does not dissociate completely into its ions when dissolved in the solution. They dissociate partially in water to release H + ions and OH − ions. Molarity ( M ) is one of the concentration terms that determine the number of moles of solute present in per liter of solution. Unit of molarity is mol/L . The mass percent of a compound is the mass of that compound in 100 g of solution.

It is not unexpected that the methoxyl substituent on a cyclohexane ring
prefers to adopt the equatorial conformation.

What is unexpected is that the closely related 2-methoxytetrahydropyran
prefers the axial conformation:

A Gp=-0.6 kcal/mol
Methoxy: CH3O group
Please be specific and clearly write the reason why this is observed. This effect that provides
stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of
example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO
interacting with anti-bonding MO...]

shown below. Circle the equilibrium reaction that would have a AG = 0, i.e., the relative energy of
the reactant (to the left of the equilibrium arrows) equals the relative energy of the product? [No
