Introduction

Metal oxides are a class of compounds that consist of a metal element bonded to one or more oxygen atoms. These compounds are widely used in various industrial applications, including catalysis, electronics, and ceramics. In this article, we will delve into the chemical composition of metal oxides, focusing on a specific example where a metal oxide with the formula MO is heated in an atmosphere of hydrogen to remove oxygen as water molecules.

Theoretical Background

The formula MO represents a metal oxide where M denotes the metal element. When this compound is heated in an atmosphere of hydrogen, the oxygen atoms are removed as water molecules (H2O). This process is known as reduction, where the metal oxide is reduced to its pure metal form. The reaction can be represented by the following equation:

MO + H2 → M + H2O

In this reaction, the metal oxide (MO) reacts with hydrogen gas (H2) to produce the pure metal (M) and water molecules (H2O).

Experimental Procedure

A 39.46 g sample of the metal oxide (MO) is strongly heated in an atmosphere of hydrogen to remove oxygen as water molecules. At the end of the reaction, 31.70 g of the metal is left. The mass of the metal oxide sample and the mass of the metal left after the reaction are given.

Calculations

To determine the atomic mass of the metal (M), we can use the following steps:

  1. Determine the mass of oxygen removed: The mass of oxygen removed can be calculated by subtracting the mass of the metal left from the mass of the metal oxide sample.

Mass of oxygen removed = Mass of metal oxide sample - Mass of metal left = 39.46 g - 31.70 g = 7.76 g

  1. Determine the number of moles of oxygen removed: The number of moles of oxygen removed can be calculated using the atomic mass of oxygen (16 g/mol).

Number of moles of oxygen removed = Mass of oxygen removed / Atomic mass of oxygen = 7.76 g / 16 g/mol = 0.486 mol

  1. Determine the number of moles of metal left: The number of moles of metal left can be calculated using the mass of the metal left and the atomic mass of the metal (M).

Number of moles of metal left = Mass of metal left / Atomic mass of metal = 31.70 g / (Atomic mass of metal)

  1. Determine the atomic mass of the metal: The atomic mass of the metal can be calculated using the number of moles of oxygen removed and the number of moles of metal left.

Since the reaction is a 1:1 ratio, the number of moles of metal left is equal to the number of moles of oxygen removed. Therefore, we can set up the following equation:

Number of moles of metal left = Number of moles of oxygen removed 31.70 g / (Atomic mass of metal) = 0.486 mol

Rearranging the equation to solve for the atomic mass of the metal, we get:

Atomic mass of metal = 31.70 g / 0.486 mol = 65.16 g/mol

Conclusion

In this article, we have demonstrated how to determine the atomic mass of a metal element using a metal oxide with the formula MO. By heating the metal oxide in an atmosphere of hydrogen, we can remove oxygen as water molecules and determine the mass of the metal left. Using the mass of the metal left and the number of moles of oxygen removed, we can calculate the atomic mass of the metal. In this example, we found that the atomic mass of the metal is approximately 65.16 g/mol.
