3.23 x 10²³ atoms
Explanation:
Given parameters:
Volume of Argon atoms = 12L
Condition = STP
Unknown:
Number of atoms = ?
Solution:
We start from the known to the unknown. We know the volume of gas at STP to be 12L;
using the equation below, we can solve for the number of moles and find the amount of atoms.
Number of moles = 
Number of moles = 
= 0.54mole
1 mole of substance contains 6.02 x 10²³ atoms
0.54 mole will contain 6.02 x 10²³ x 0.54 = 3.23 x 10²³ atoms

No, it doesn't. According to huckle rule it must have 14 \pi<span> electrons to be aromatic but it has only 12 pi electrons. then how does it follow the rule?
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

The protons are equivalent to the atomic number, so we can determine that the element being expressed here is Magnesium. If you are ever stuck on what element you are finding your information from, just remember that the number of protons is the exact same as the atomic number in ANY situation :)
The charge of magensium is +2, with an atomic mass of 24. So A would be your answer :)
