Explanation:
1. Write the equation for the half-reaction.
Mg²⁺ + 2e⁻ ⟶ Mg
The number of electrons transferred (z) is 2 mol per mole of Mg.
2. Calculate the number of coulombs
Q = It
3. Mass of Mg
We can summarize Faraday's laws as
The molar mass of is 86.02 g/mole
.
The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.
The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.
From the below attached table, the Molar mass of is 86.0108 g/mol.
