Cell division. Hope this helps :)
Answer:
The answer to your question is Molarity = 0.238
Explanation:
Data
Molarity = ?
number of moles = 0.285
volume = 1.2 L
Molarity is a unit of concentration that relates the moles of a substance by the volume in liters.
Formula
Molarity = moles / volume
Substitution
Molarity = 0.285 / 1.2
Simplification and result
Molarity = 0.238
Ecell = E°cell - RT/vF * lnQ
R is the gas constant: 8.3145 J/Kmol
T is the temperature in kelvin: 273.15K = 0°C, 25°C = 298.15K
v is the amount of electrons, which in your example seems to be six (I'm not totally sure)
F is the Faradays constant: 96485 J/Vmol (not sure about the mol)
Q is the concentration of products divided by the concentration of reactants, in which we ignore pure solids and liquids: [Mg2+]³ / [Fe3+]²
Standard conditions is 1 mol, at 298.15K and 1 atm
To find E°cell, you have to look up the reduction potensials of Fe3+ and Mg2+, and solve like this:
E°cell = cathode - anode
Cathode is where the reduction happens, so that would be the element that recieves electrons. Anode is where the oxidation happens, so that would be the element that donates electrons. In your example Fe3+ recieves electrons, and should be considered as cathode in the equation above.
When you have found E°cell, you can just solve with the numbers I gave you.

Explanation:
Ammonium nitrate is a chemical compound, the nitrate salt of the ammonium cation. It has the chemical formula NH ₄NO ₃, simplified to N₂H₄O₃. It is a white crystalline solid and is highly soluble in water. It is predominantly used in agriculture as a high-nitrogen fertilizer.
