Explanation:
The orbital diagram of an electron with eight electron is attached. Since the 2p orbitals are filled using the maximum space available instead of pairing the electrons, this is in accord with Hund's rule.
When filling orbitals, you should put one electron in each box. After all of the boxes in the orbital have one electron in each, you can then put the second electron into each of the boxes.
Molarity is one of the method of expressing concentration of solution. Mathematically it is expressed as,
Molarity =
Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l
∴ 5 =
∴
number of moles = 3.75Answer: Number of moles of KOH present in solution is 3.75.

0.025 M will be the resulting concentration
Explanation:
To find the resulting concentration we use the following formula:
initial concentration × initial volume = final concentration × final volume
initial concentration = 0.15 M
initial volume = 2 mL
final concentration = ?
final volume = 10 + 2 = 12 mL
0.15 × 2 = final concentration × 12
final concentration = (0.15 × 2) / 12
final concentration = 0.025 M
