B) CH3 and C2H6
C) C3H8 and C3H6
D) C2H2 and C2H4

Explanation:The empirical formula of a compound has the simplest possible integer ratio of atoms.   We see that only have the same empirical formula.

A) C2H6O1To find the emperical formula, divide each mole value by the smallestFor carbon, 0.013/0.0065 = 2 For hydrogen, 0.038/0.0065= 6For oxygen, 0.0065/0.0065= 1Emperical formula = C2H6O1

Raphaelle Dietrich · Answer

Answer : The correct option is .Explanation :Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.The given molecular formula is .For the empirical formula, the actual number of atom in is divided by 2.So, the empirical formula is .

C2H6O1Explanation:Empirical formula means to express the ratio of the number of atoms , i.e to identify which of the three elements appears with the smallest number of atoms in the formula, and then to get the rate of the atoms belonging to other species in respect with this one. In this molecule Oxygen shows the smallest number of moles (0.0065)  (O1)To see how many moles of carbon correspond to 1 mole of Oxygen, divide 0.013 moles of C to 0.0065 moles of Oxygen:  0.013/0.0065 =2 Therefore for each mole of Oxygen you have two moles of C (C2)To see how many moles of Hydrogen correspond to 1 mole of Oxygen, divide 0.039 moles of H to 0.0065 moles of Oxygen:  0.039/0.0065 =6 Therefore for each mole of Oxygen you have six moles of H  (H6)The empirical formula is C2H6O1

Empirical formula for is Explanation:Empirical formula of a molecule contains symbol of all constituent atoms along with their lowest possible stoichiometric coefficient.In , stoichiometric coefficients of C and H are 2 and 6 respectively.We can write this formula as – So clearly the lowest possible stoichiometric coefficients of C and H would be  1 and 3 respectively.So empirical formula is

The empirical formula of the given compound is Explanation:Empirical formula is defined number of ratio of elements present in the molecule but do not tell the total number of atoms of each atom or atomic arrangement.The empirical formula of the given compound: We will divide the all the number of atoms of element in the molecule formula of the compound with an whole number in order to obtain the smallest whole number.The empirical formula of :The empirical formula of the given compound is

I think the correct answer from the choices listed above is option A. The additional piece of information needed to determine the molecular formula would be percent composition of carbon. A molecular formula is a formula that gives the number of atoms of each of the elements present in one molecule of a specific compound.
