The image above represents normally occupied positions.

To compute for 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 o**ccupied positions:

N = ^{NAρ }/ _{(AK + AG)}

N = Normally Occupied Positions

N_{A} = Avogadro’s Number

A_{K}, A_{G} = Atomic Weights

ρ = Density

Let’s solve an example;

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 that;

N_{A} = Avogadro’s Number = 6.022e+23

A_{K}, A_{G} = Atomic Weights = 12, 16

ρ = Density = 10

N = ^{NAρ }/ _{(AK + AG)}

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 is Given.**

ρ = ^{N (AK + AG)} / _{NA}

Where;

ρ = Density

N = Normally Occupied Positions

N_{A} = Avogadro’s Number

A_{K}, A_{G} = Atomic Weights

Let’s solve an example;

Given that normally occupied positions is 20, the avogadro’s number is 6.022e+23, atomic weights is 18, 6.

This implies that;

N = Normally Occupied Positions =20

N_{A} = Avogadro’s Number = 6.022e+23

A_{K}, A_{G} = Atomic Weights = 18, 6

ρ = ^{N (AK + AG)} / _{NA}

ρ = ^{20 (18 + 6)} / _{6.022e+23}

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}) is Given.**

A_{K} = ^{NAρ} / _{N} – A_{G}

Where;

ρ = Density

N = Normally Occupied Positions

N_{A} = Avogadro’s Number

A_{K}, A_{G} = Atomic Weights

Let’s solve an example;

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 that;

ρ = Density = 12

N = Normally Occupied Positions = 24

N_{A} = Avogadro’s Number = 6.022e+23

A_{G} = Atomic Weights = 10

A_{K} = ^{NAρ} / _{N} – A_{G}

A_{K} = ^{6.022e+23 x 12} / _{24} – 10

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}) is Given.**

A_{G} = ^{NAρ} / _{N} – A_{K}

Where;

ρ = Density

N = Normally Occupied Positions

N_{A} = Avogadro’s Number

A_{K}, A_{G} = Atomic Weights

Let’s solve an 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 that;

ρ = Density = 10

N = Normally Occupied Positions = 10

N_{A} = Avogadro’s Number = 6.022e+23

A_{G} = Atomic Weights = 4

A_{G} = ^{NAρ} / _{N} – A_{K}

A_{G} = ^{6.022e+23 x 10} / _{10} – 4

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.**
