The mass percent of oxygen in zinc bromate is a crucial aspect of understanding its chemical composition and properties. This concept measures the concentration of oxygen within the zinc bromate compound, providing valuable insights into its molecular structure and behavior.
Delving into the composition of zinc bromate, we identify the presence of zinc, bromine, and oxygen atoms. By determining the molar mass of zinc bromate, we establish the relative proportions of these elements. Subsequently, we calculate the molar mass of oxygen and determine the number of moles of oxygen present in one mole of zinc bromate.
Mass Percent of Oxygen in Zinc Bromate
Zinc bromate is a chemical compound with the formula Zn(BrO3)2. It is a white, crystalline solid that is soluble in water. Zinc bromate is used as a source of bromine in various industrial processes.
Definition of Mass Percent
Mass percent is a measure of concentration that expresses the amount of a substance in a mixture as a percentage of the total mass of the mixture. It is calculated using the following equation:
“`Mass percent = (Mass of substance / Total mass of mixture) x 100%“`
Composition of Zinc Bromate
Zinc bromate is composed of the following elements:
- Zinc (Zn)
- Bromine (Br)
- Oxygen (O)
The molar mass of zinc bromate is 339.22 g/mol.
Mass of Oxygen in Zinc Bromate
The molar mass of oxygen is 16.00 g/mol.
There are six moles of oxygen in one mole of zinc bromate.
The mass of oxygen in one mole of zinc bromate is 96.00 g.
Mass Percent of Oxygen in Zinc Bromate
The mass percent of oxygen in zinc bromate is calculated using the following equation:
“`Mass percent of oxygen = (Mass of oxygen / Total mass of zinc bromate) x 100%“`
Substituting the values we have calculated, we get:
“`Mass percent of oxygen = (96.00 g / 339.22 g) x 100% = 28.30%“`
Therefore, the mass percent of oxygen in zinc bromate is 28.30%.
