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).

When water condenses, aka changes from gas to liquid, it releases the most heat energy. Your answer is condensation.
The complete question is as follows: How many moles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa
Answer: There are 0.0489 moles of a gas at 
is required to fill a 1.00 l flask to a pressure of 152kPa.
Explanation:
Given: Volume = 1.00 L,
Pressure = 152 kPa (1 kPa = 1000 Pa) = 152000 Pa
Convert Pa into atm as follows.
Temperature = 
Using the ideal gas formula as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Thus, we can conclude that there are 0.0489 moles of a gas at is required to fill a 1.00 l flask to a pressure of 152kPa.
