What is Metal Weight?

Metal weight, in the context of chemistry, refers to the mass of a single atom of a metal element. It is derived from the atomic weight and valency of the metal. Understanding metal weight is crucial in various chemical calculations, particularly in stoichiometry and metallurgy.

Formula

The formula to calculate the weight of one atom of a metal is:

\[ \text{Metal Weight} = \frac{\text{Atomic Weight}}{\text{Valency}} \]

Where:

• \(\text{Metal Weight}\) is the weight of one atom of the metal (g/mol)
• \(\text{Atomic Weight}\) is the average mass of atoms of an element (g/mol)
• \(\text{Valency}\) is the combining capacity of the metal

Calculation Steps

Let's calculate the metal weight for iron (Fe):

• Atomic Weight of Fe = 55.85 g/mol
• Valency of Fe = 3 (in its most common oxidation state)

1. Apply the formula: \[ \text{Metal Weight} = \frac{\text{Atomic Weight}}{\text{Valency}} \]
2. Substitute the values: \[ \text{Metal Weight} = \frac{55.85 \text{ g/mol}}{3} \]
3. Calculate: \[ \text{Metal Weight} = 18.62 \text{ g/mol} \]
