Determine the molecular formula of a compound if its empirical formula is C2H6O and its molar mass is 138g?
Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula. x ( MM of empirical formula ) = MM of molecular formula MM of empirical formula = 12(2) + 1(6) + 16 = 46 MM of molecular formula = 138 46x = 138 x= 138 / 46 x=3 Therefore, the molecular formula is 3(C2H6O) that is C6H18O3
Two compounds that have the same molecular formula but different structural formulas are?
Two compounds that have the same molecular formula but different structural formulas are isomers. Isomers are compounds with the same number and types of atoms but arranged differently. An example is ethanol (C2H6O) and dimethyl ether (C2H6O), both have the same molecular formula but different structural formulas.
Is ethanol a mixture or compound?
Ethanol is a compound (organic). Ethanol is abbreviated as EtOH, using the common organic chemistry notation of representing the ethyl group (C2H5) with Et. This designation is used both by EMS and Hospital ER staff when describing alcohol intoxication, and is found in most chemistry textbooks as well.Ethanol is a straight-chain alcohol, and its molecular formula is C2H5OH. An alternative notation is CH3-CH2-OH, which indicates that the carbon of a methyl group (CH3-) is attached to the carbon of a methylene group (-CH2-), which is attached to the oxygen of a hydroxyl group (-OH). Its empirical formula is C2H6O, making it an isomer of dimethyl ether.
What does a structural formula depict that a molecular formula does not?
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
Three elements in the compound called ethanol?
Carbon, hydrogen, and oxygen are the three elements present in the compound ethanol. Ethanol has the chemical formula C2H6O.
Is alcohol an compound or a mixture?
Alcohol is a compound. Pure alcohol is made up of molecules of ethanol. It's molecular formula is C2H6O.
What is the formula mass for C2H6O?
Methane is an elementary organic compound having the molecular formula of CH4. Methane is composed of carbon (C) and hydrogen (H) atoms. The molecular weight of CH4 is 16. 01 grams per mole.

What are Chemical formulas for ethanol?
The molecular formula of ethanol is written as either CH3CH2OH or C2H5OH, and its empirical formula is C2H6O. It is often written as EtOH.
Two compounds that have the same molecular formula but different structural formulas are?
Two compounds that have the same molecular formula but different structural formulas are isomers. Isomers are compounds with the same number and types of atoms but arranged differently. An example is ethanol (C2H6O) and dimethyl ether (C2H6O), both have the same molecular formula but different structural formulas.
Do you have a list of common molecular formulas?
Some common molecular formulas include H2O for water, NaCl for salt, C12H22O11 for sugar, and C2H6O for alcohol. The molecular formula for vinegar is CH3COOH.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
What is the molecular formula for ethanal?
Ethanol, or drinking alcohol, is a solvent and reagent with the chemical formula CH3CH2OH.Ethanal, better known as acetaldehyde, is an aldehyde with the formula CH3CHO.
What is the chemical compound in whiskey and what is the symbols?
Whiskey contains more than one chemical compound, but the "active ingredient" for those who regard whiskey as a medicine is ethanol, alternatively called "ethyl alcohol". Its molecular formula is C2H6O, more often written as H3CCH2OH or CH3CH2OH.
Is c2h6o ionic molecuAR OR NEITHER?
First of all , what is 'c2h6o'??? If you mean C2H6O , then the formula is usually written as CH3CH3OH CH3CH2OH is ethanol ( acetyl alcohol) The alcohol that humans frink in beers, wines, and spiritis. It is a COVALENT molecule. It does not have ionic tendences. However, the 'OH' functional group can be substituted for an halogen or amine. NB When writing chemical formula . For single letter elemental symbols it is a CAPITAL letter 'C' for carbon, not 'c' . Similrly 'H' & 'O'. For two letter symbols , first letter is a capital letter and the second leetter is small/lower case. e.g. 'Na' ( Sodium' Latin for Nadium). NNB You misunderstand between 'Ionic' and 'Molecular'. All substances are 'molecules'. The bonding within substances can be either 'Ionic' or 'covalent'.
