The volume of 0.125 mole of the gas at the same temperature and pressure 0.30 L
<h3>Data obtained from the question </h3>
- Initial mole (n₁) = 0.82 mole
- Initial volume (V₁) = 2 L
- New mole (n₂) = 0.125 mole
- Pressure = Constant
- Temperature = Constant
- New Volume (V₂) =?
<h3>How to determine the new volume</h3>
The new volume can be obtained as illustrated below
PV = nRT
Divide both side by P
V = nRT / P
Divide both side by n
V / n = RT / P = Constant
Thus,
V₁ / n₁ = V₂ / n₂
2 / 0.82 = V₂ / 0.125
Cross multiply
0.82 × V₂ = 2 × 0.125
Divide both side by 0.82
V₂ = (2 × 0.125) / 0.82
V₂ = 0.30 L

Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
Magnetic quantum number :
The magnetic quantum number is
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.
