YES.For one to know the percentage composition,the amount of moles of the reacting element must be considered using the compound.
•Well you dont really have to know just the formula. You can eaither use the formula if its given or the molar mass if its given. i just recently did a test where i was given either the Molar mass or Formula name and i had to figure out the percent composition. so it depends on the info given.

Does percentage calculation require the chemical formula of the solute?
For mass % only the mass is required for this calculation. When only moles are known, than also molar composition - formula and atomic- or molecular masses are needed to calculate % of composition
What information in a chemical formula mean?
The chemical formula is representative for the chemical composition of a chemical compound.
What is the chemical formula for duct tape?
Duct tape is a mixture, not a compound and composition can vary with brand. Therefore, there is no chemical formula.

What do you need to calculate the percent-age composition of a substance?
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
What is the importance of percentage composition?
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
What does a formula tells about a compound?
