How to Calculate and Solve for Normally Occupied Positions | Ceramics

The image above represents normally occupied positions in ceramics. To calculate normally occupied positions, four essential parameters are needed, and these parameters are Avogadro’s number (N_A), Density (ρ), Atomic weight (A_K) and Atomic weights (A_G).

The Formula for Calculating Normally Occupied Positions

N = ^N_Aρ / _{(AK + AG)}

N = Normally Occupied Positions
N_A = Avogadro’s Number
A_K, A_G = Atomic Weights
ρ = Density

Let’s solve the following example below:
Find the normally occupied positions when the avogadro’s number is 6.022e+23, atomic weight is 12, atomic weight is 16 and the density is 10.

This implies the following;

N_A = Avogadro’s Number = 6.022e+23
A_K, A_G = Atomic Weights = 12, 16
ρ = Density = 10

N = ^N_Aρ / _{(AK + AG)}
So, N = ^{(6.022e+23)(10)}/_{(12 + 16)}
N = ^(6.022e+24)/₍₂₈₎
N = 2.15e+23

Therefore, the normally occupied positions is 2.15e+23.

Calculating the Density when the Normally Occupied Positions, the Avogadro’s Number, the Atomic Weights are Given

ρ = ^{N (A_K + A_G)} / _NA

Where;

ρ = Density
N = Normally Occupied Positions
N_A = Avogadro’s Number
A_K, A_G = Atomic Weights

Let’s solve the following example below:
Given that normally occupied positions is 20, the avogadro’s number is 6.022e+23, atomic weights is 18, 6.

This implies the following:

N = Normally Occupied Positions =20
N_A = Avogadro’s Number = 6.022e+23
A_K, A_G = Atomic Weights = 18, 6

ρ = ^{N (A_K + A_G)} / _NA
ρ = ^{20 (18 + 6)} / _6.022e+23
Then, ρ = ^{20 (24)} / _6.022e+23
ρ = ⁴⁸⁰ / _6.022e+23
ρ = 7.970e-22

Therefore, the density is 7.970e-22.

Calculating the Atomic Weight (A_K) when the Normally Occupied Positions, the Avogadro’s Number, Density and Atomic Weight (A_G) are Given

A_K = ^N_Aρ / _N – A_G

Where;

ρ = Density
N = Normally Occupied Positions
N_A = Avogadro’s Number
A_K, A_G = Atomic Weights

Let’s solve the following example below:
Find the atomic weight when the normally occupied positions is 24, the density is 12, the avogadro’s number is 6.022e+23 and the atomic weight is 10.

This implies the following:

ρ = Density = 12
N = Normally Occupied Positions = 24
N_A = Avogadro’s Number = 6.022e+23
A_G = Atomic Weights = 10

Then, A_K = ^N_Aρ / _N – A_G
A_K = ^{6.022e+23 x 12} / ₂₄ – 10
That is, A_K = ^7.2264e+24 / ₂₄ – 10
A_K = 3.011e-23 – 10
A_K = – 6.98e-23

Therefore, the atomic weight is – 6.98e-23.

Calculating the Atomic Weight (A_G) when the Normally Occupied Positions, the Avogadro’s Number, Density and Atomic Weight (A_K) are Given

A_G = ^N_Aρ / _N – A_K

Where;

ρ = Density
N = Normally Occupied Positions
N_A = Avogadro’s Number
A_K, A_G = Atomic Weights

Let’s solve for the following example:
Find the atomic weight when the normally occupied positions is 10, the density is 10, the avogadro’s number is 6.022e+23 and the atomic weight is 4.

This implies the following:

ρ = Density = 10
N = Normally Occupied Positions = 10
N_A = Avogadro’s Number = 6.022e+23
A_G = Atomic Weights = 4

So, A_G = ^N_Aρ / _N – A_K
A_G = ^{6.022e+23 x 10} / ₁₀ – 4
That is, A_G = ^6.022e+24 / ₁₀ – 4
A_G = 6.022e-23 – 4
A_G = 2.022e-23

Therefore, the atomic weight is 2.022e-23.
