Answer 1

where is the expression...???

Answer 2

Answer:

(D) Cu + Hg$^{2+}$ → Cu$^{2+}$ Hg is correct for ‘Ka’ in terms of Λ° and Λ, where ‘C’ is molarity.

Explanation:

Molar concentration is a unit of measurement for the concentration of a chemical species, specifically a solute, in a solution, expressed as the amount of substance per unit volume of solution. The most commonly used unit for molarity in chemistry is the number of moles per litre, denoted by the unit symbol  mol/L or mol/dm³ in SI unit.

Molar concentration, also known as molarity, is the number of moles of a solute in one litre of solution. The following formula can be used to calculate it:

C = molar concentration in mol/L or M;

m = solute mass in grams (g).
