Step 1. Divide each by its Atomic Mass.
H 2.4 / 1 = 2.4
S 39 / 32 = 1.21875
O 58.6 / 16 = 3.6625
Step 2. Compare answers, pick smallest one and divide all answers by that smallest.
H 2.4 / 1.21875 = 1.969
S 1.21875 / 1.21875 = 1
O 3.6625 / 1.21875 = 3.005
Step 3. Look at the decimal parts, if they are close to a whole number round to a whole number --- these become subscripts for the formula.

How do you know if a formula is an empirical formula?
An empirical formula has no data about the structure of a compound.
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!)
What is the empirical formula of a compound that contains 75 percent Ag and 25 percent Cl by mass?
AgCl
Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
What is the most likely empirical formula for a compound that contains 55.85 grams of iron and 106.5 grams of chlorine?
FeCl3
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
Explain Why is H2O2 is not the empirical formula of hydrogen peroxide?
An empirical formula is the lowest ratio of elements in a compound. So since H2O2 can be reduced to HO (H1O1), that is the empirical formula. The molecular formula is H2O2.
What is the empirical formula for the compound X39Y13?
X3Y is the empirical formula
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.
A compound contains 21.2%N 6.1%H 24.2% and 48.5%O What is it’s empirical formula?
The empirical formula of a compound that consists of 21.2%N, 6.1%H, 24.2% S and 48.5% O is N2H8SO4.
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
empirical formula of a 9.50g sample of a compound that contains 3.03g of K 2.75g Cl and O?
This compound is potassium oxide, K2O.
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
