To find the percentage composition of a compound, the steps should be arranged in the following logical sequence:
- Identify the correct chemical formula for the compound.
- Count out the atoms of each element using subscripts when needed.
- Multiply the numbers of atoms of each element by the mass from the periodic table to find the molar mass of the compound.
- Divide the mass of the individual element by the molar mass of the entire compound and multiply by 100 for each element.
