What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
The empirical formula for cumene a compound containing only carbon and hydrogen is C3H4. Its Molecular mass is 120 g. What is the molecular formula for cumene?
This molecular formula is C9H12.
What are the elements in mothballs?
From the Wikipedia article on mothballs, "Older mothballs consisted primarily of naphthalene, but due to naphthalene's flammability, modern mothballs instead use 1,4-dichlorobenzene (also called para-dichlorobenzene, p-dichlorobenzene, or PDB)."
What is the molecular formula of a compound that has a mass of 54 and an empirical formula of c2h2?
This is a hydrocarbon called Acetylene (IUPAC name : Ethyne). It contains two carbon atoms joined with a triple bond, and 2 hydrogen atoms connected to the two carbon atoms with a single bond. Its structure : H-C≡C-H
What is the empirical formula of diamond?
Just C because it is a carbon allotrope
What is the empirical formula of the compound that is 75 carbon and 25 hydrogen?
The empirical formula of a compound is the simplest whole number ratio of the elements in the compound. In C75H25, the ratio of carbon to hydrogen is 75:25, which is equal to 3:1. Thus, the empirical formula is C3H.
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
The empirical formula is CH2
What is the percent composition of a compound with the empirical formula CO2?
One atom of carbon, two of oxygen.

What is the empirical formula of a substance that contains 0.117 of carbon 0.233 of hydrogen and 0.117 of oxygen?
Ch2o
What is the relationship between the empirical formula and the molecular formula?
An empirical formula contains the constituent elements in the lowest possible mathematical whole-number ratio. In some cases, this is the legitimate formula for the compound, particularly if the substance you're dealing with is an ionic compound. Sometimes, however, the actual formula, known as the molecular formula, is a whole-number multiple of the empirical formula. The molecular formula for glucose is C6H12O6. However, an empirically-derived formula for glucose would be CH2O, which is the lowest possible ratio of carbon, hydrogen, and oxygen in that compound.
Empirical formulas describe the types of atoms in a compound and their?
An empirical formula give information about the chemical composition of a compound. Example: tetracycline with the empirical formula C22H24N2O8 has the following composition: - carbon 59,44 % - oxygen 28,81 % - nitrogen 6,30 % - hydrogen 5,45 % If you're with plato the answer is ratios
Does CO2 and SO2 have the same empirical formula?
No, Compounds with the same empirical formula have the same elements in the same ratio. SO2 and CO2 contain different elements. SO2 is a compound of sulfur and oxygen while CO2 is a compound of carbon and oxygen.
What is the empirical formula of a compound which is 64.80 percent carbon 6.35 percent hydrogen and 28.83 percent sulfur?
C4h2s
What is the compound that has an empirical formula of CH2?
C12h24
The empirical formula for cumene a compound containing only carbon and hydrogen is C3H4. Its Molecular mass is 120 g. What is the molecular formula for cumene?
This molecular formula is C9H12.
What is the emprical formula for the compound that contains 20 percent hydrogen and 80 percent carbon?
The atomic mass of hydrogen is 1 and that of carbon is 12, to the nearest integer. Therefore, a compound that contains 20 percent hydrogen and 80 percent carbon contains atoms of carbon in the ratio of 20:(80/12) = 20:(20/3) = 20 X 3/20 = 3. The smallest whole number ratio corresponding to this is 1:3, which corresponds to an empirical formula of CH3. (However, since carbon normally has a valence of 4 in hydrocarbons, the actual formula is probably C2H6.)
