Question

Sally has constructed a concentration cell to measure ksp for mcln. She constructs the cell by adding 2 ml of 0.05 M M(NO₃)N to one compartment of the microwell plate. She then makes a solution of MCLN by adding KCl to M(NO₃)N. She adds 0.612 ml of the resulting mixture to a second compartment of the microwell plate. Sally knows n (the charge on the metal ion) = 1. She has already calculated [Mn] in the prepared MCLN solution using the Nernst equation. [Mn] = 5.387 M. How many moles of [Mn] are dissolved in that compartment of the microwell plate?

Answer 1

To determine the number of moles of [Mn] dissolved in the compartment of the microwell plate, we need to use the Nernst equation and the given concentration of [Mn]. However, without the measured voltage, we cannot calculate the number of moles.

Step-by-step explanation:

To determine the number of moles of [Mn] dissolved in the compartment of the microwell plate, we need to use the Nernst equation and the given concentration of [Mn]. The Nernst equation is given by: Ecell = E°cell - (0.0592/n)log([Mn])

Given that n (the charge on the metal ion) is 1 and the calculated concentration of [Mn] is 5.387 M, we can substitute these values into the Nernst equation:

Ecell = E°cell - (0.0592/1)log(5.387)

Simplifying this equation gives us:

Ecell = E°cell - 0.0592log(5.387)

Since the measured voltage (Ecell) in the compartment is not given, we cannot directly calculate the number of moles of [Mn] dissolved. The voltage measurement is needed to determine E°cell, which would allow us to solve for the number of moles of [Mn]. Without this information, we cannot provide an answer to the question.
