Which element requires the least amount of
energy to remove the most loosely held electron
from a gaseous atom in the ground state?
<h3>Answer-</h3><h3>Na</h3>
Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution: Molarity (M) = moles solute. liters solution.
Answer:
Oxygen comes 8th on the periodic table which is the atomic number.
Explanation:
but Oxygen 13 (Isotopes of Oxygen) is when oxygen has 8 protons and electrons, and 5 neutrons (8+5=13)
Molarity = moles of solute(HCl)

= 0.2M.
Hence option B is correct.
Hope this helps!!
