Answer:
1.29* 10^2
Explanation:
multiply them and then round
The number of electrons in an atom which has its quantum number n equal to 2 (n = 2) and ml equal to 2 (ml = 2) is equal to zero (0).
<h3>What is an electron?</h3>
An electron can be defined as a subatomic particle that is negatively charged and it's found outside the nucleus of the atom of a chemical element. This ultimately implies that, an electron is the opposite of a subatomic particle called proton.
<h3>What is the Pauli exclusion principle?</h3>
The Pauli exclusion principle can be defined as a principle which states that no two electrons (fermions) in a single atom can have the same numerical values for all four (4) of their electronic quantum numbers.
Furthermore, this principle states that the orbital of an atom can only contain a maximum of two (2) electrons, and they must have opposing spin orientations.
Based on Pauli exclusion principle, we can infer and logically deduce that the number of electrons in an atom which has its quantum number n equal to 2 (n = 2) and ml equal to 2 (ml = 2) would be equal to zero (0).

The four organelles that process, transport, and have some materials are the nucleus and ribosomes the genetic control of the cell. Endoplasmic reticulum that make, distribute, and break down molecules. Mitochondria and chloroplasts for energy processing. Lastly the cytoskeleton, plasma membrane, and cell wall
To be able to determine the number of moles that a certain number of molecules comprises, we simply divide the number of molecules by the Avogadro's number which is equal to 6.022 x 10^23.
n = M/A
where n is the number of moles, M is the number of molecules, and A is Avogadro's number. Substituting the known values,
n = (4.15 x 10^23 molecules)/(6.022 x 10^23 molecules/mol)
Simplifying,
n = 0.689 moles
<em>Answer: 0.689 moles</em>
