How many o2 particles are in 2.50 of o2 at standard temperature and pressure (stp)? a. 4.15 x 10^22 particles b. 2.41 x 10^23 particles c. 5.02 x 10^23 particles d. 1.51 x 10^24 particles can you explain the answer ?

The correct answer is Option D.

Explanation:

To calculate the number of atoms, we take the help of mole concept.

According to mole concept:

1 mole of any element contains number of atoms.

We need to find the number of particles or atoms present in 2.5 mole of gas:

2.50 moles of gas will have =

Hence, the correct answer is Option D.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
