If one of the atoms is already at its smallest amount. i.e. CH4 would be the same for both, while C2H8 would also have an empirical formula of CH4 though.

H2O --> H2O etc.

CH4 has the same molecular and empirical formulas.


The molecular formula is the same as the empirical formula, NO2. The compound NO2 has a molar mass of 46g/mol, so the empirical and molecular formulas are the same.


Both formulas are possible molecular formulas for the same empirical formula, CH2.


Molecular formula is the integral multiple of Empirical formula.


Example of Empirical formula is : CO2 Example of Molecular formula is : C4O8


Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.


The same as its molecular formula; CH4. See related question below for more details on how to find empirical formulas.


An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.


A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.


These two compounds has different molecular formulas.


Yes they can. For example CH2O is the empirical formula for both formaldehyde(CH2O) and glucose(C6H12O6)


Empirical formulas show the simplest whole number ratio of these atoms. Molecular formulas show the actual ratio of atoms in the compound. For example: Glucose is the a simple sugar whose molecular formula is C6H12O6 Its empirical formula would be CH2O which would be its molecular formula divided by the smallest whole number. Chemical Name Hydrogen peroxide Empirical Formula HO Molecular Formula H2O2 chemical name Benzene empirical formula CH molecular formula C6H6 remember that several compounds can have the same empirical formula


The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.


The emprical formula is C5H4. The molecular formula is C10H8.



The similarity Is that you can find the components of the compound from both formulas


For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)


The empirical formula tells you the simplest formula for the compound. The molecular formula will be some multiple of the empirical formula, or it can be identical to the empirical formula.


CCl4 is the molecular formula for carbon tetrachloride. It is the same as its empirical formula.


Imperical fomula is C2H4.Molecular fomula is C4H8.


In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.


the empirical formula only gives the amount of each element as a ratiothe molecular formula gives the actual number of atoms of each element in a molecule of the compoundFor example these compounds all have the same empirical formula (CH2) but different molecular formulas: ethylene C2H4butene C4H8cyclohexane C6H12cyclooctane C8H16cyclodecane C10H20etc.


C6H10OS2. Molecular and empirical are the same for Allicin.


"Molecular formulas show the total number of each atom in the molecule. Empirical formulas only show the ratio of the elements in the molecule. For example - acetate Molecular Formula Empirical Formula C6H12O6 CH2O " I just wanted to note that although this is correct the chemical formula in the example "C6H12O6" is not acetate. It is glucose. Acetate is a derivative of acetic acid.


MF C12H22O11 EF same notice since 11 is prime no number will divide all
