What is the empirical formula for naphthalene?

Thus naphthalene contains a 1.25:1 ratio of moles of carbon to moles of hydrogen: C1.25H1.0. Because the ratios of the elements in the empirical formula must be expressed as small whole numbers, multiply both subscripts by 4, which gives C5H4 as the empirical formula of naphthalene.

How do you find a empirical formula?

Calculate the empirical formula.

  1. In any empirical formula problem you must first find the mass % of the elements in the compound.
  2. Then change the % to grams.
  3. Next, divide all the masses by their respective molar masses.
  4. Pick the smallest answer of moles and divide all figures by that.

What is the difference between a molecular formula and an empirical formula?

Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.

What is chemical formula of naphthalene?

Naphthalene is a carbon-based chemical that is most commonly used to make mothballs. It has the chemical formula C 10H 8, and is known within the scientific community as a polycyclic aromatic hydrocarbon. This chemical is found in nature but scientists can also synthetically create it in a lab.

What is the molar mass of naphthalene?

The molar mass of naphthalene is 128.17052 g/mol. Naphthalene’s chemical formula C10 H8 tells us that there are 10 carbon atoms and 8 hydrogen atoms.

What are some examples of empirical formulas?
