Free-energy change, ΔG∘, is related to cell potential, E∘, by the equation ΔG∘=−nFE∘ where n is the number of moles of electrons
elena-s [515]

Answer:

-372000 J or -372 KJ

Explanation:

We have the electrochemical reaction as;

Mg(s)  +  Fe^2+(aq)→  Mg^2+(aq)  +   Fe(s)

We must first calculate the E∘cell from;

E∘cathode -  E∘anode

E∘cathode = -0.44 V

E∘anode = -2.37 V

Hence;

E∘cell = -0.44 V -(-2.37 V)

E∘cell = 1.93 V

n= 2 since two electrons were transferred

F=96,500C/(mol e−)

ΔG∘=−nFE∘

ΔG∘= -( 2 * 96,500 * 1.93)

ΔG∘= -372000 J or -372 KJ

What is the concentration of a solution that has a volume of 2.5L and contains exactly 2.125 moles of calcium phosphate
Iteru [2.4K]

Answer:

0.85 mol/L.

Explanation:

  • Molarity is defined as the no. of moles of solute dissolved in a liter of the solution.

<em>M = (no. of moles of solute)/(Volume of the solution (L))</em>

no. of moles of calcium phosphate = 2.125 mol.

Volume of the solution = 2.5 L.

<em>∴ M of calcium phosphate</em> = (2.125 mol)/(2.5 L) = <em>0.85 mol/L.</em>
