Under equilibrium condition, what is the probability of an electron state being occupied if it is located at the Fermi level
Sav [38]

Answer:

Hi

The Fermi Level is a term used to describe the set of electron energy levels at a temperature of absolute zero. Fermi's energy concept is important for the understanding of the electrical and thermal properties of solids. Both electrical and thermal processes involve energy values of a small fraction of an electron-volt. In thermal equilibrium, the net current of both electrons and holes is zero.

1. Calculate the molar mass of the substances involved in the reaction
Nookie1986 [14]

The molar mass of a substance/chemical is the mass of the sample substance divided by the  amount of substance in that sample.

Explanation:

  • In order to calculate the atomic mass of a substance we first obtain the atomic weight of the substance from the periodic table.
  • Then we count the number of atoms of the substance and multiply it with the individual atomic mass.

Molar mass of Citric Acid ( H3C6H5O7) is 192.1235 g/mol

It is calculated as :

Molar mass of C₆H₈O₇ = 6(atomic mass of C) + 8(atomic mass of H) + 7(atomic mass of O) = 6(12.0 g/mol) + 8(1.0 g/mol) + 7(16.0 g/mol) = 192.0 g/mol.

Molar mass of baking soda (NaHCO₃) is 84.0 g/mol

Molar mass of NaHCO₃ = (atomic mass of Na) + (atomic mass of H) + (atomic mass of C) + 3(atomic mass of O) = (23.0 g/mol) + (1.0 g/mol) + (12.0 g/mol) + 3(16.0 g/mol) = 84.0 g/mol.
