Question

Place the steps for finding percentage composition of a compound in the most logical sequence.(4 points)

identified the correct chemical formula for the compound
count out the atoms of each element using subscripts when needed
divide the mass of the individual element by the molar mass of entire compound and multiply by 100 for each elemtn
multiply the numbers of atoms of each element by the mass from the periodic table to find the molad mass of compound

Answer 1

To find the percentage composition of a compound, the steps should be arranged in the following logical sequence:

1. **Identify the correct chemical formula for the compound.**
2. **Count out the atoms of each element using subscripts when needed.**
3. **Multiply the numbers of atoms of each element by the mass from the periodic table to find the molar mass of the compound.**
4. **Divide the mass of the individual element by the molar mass of the entire compound and multiply by 100 for each element.**
