The molecular formula provides the actual number of atoms present in each kind of molecule. From the above solution, the empirical formula of said organic compound in chemistry, C 3H 6O 2. How to find the empirical formula of the compound in chemistry?Īnswer: Weight of carbon in the said compound = (12/44) × 0.361 gm = 0.0985 gm, weight of the hydrogen = (2/18) × 0.147 = 0.0163 gm, and weight of oxygen = 0.202 – (0.0985 + 0.0163) = 0.0872 gm.
Question: If 0.202 gm of an organic compound gave on combustion 0.361 gm of carbon dioxide and 0.147 gm of water.
The empirical formula in chemistry defines the relative number of each class of atom in the general molecular formula that helps for the calculation of percentage composition or chemical structure of the molecule or compound.
