What is the empirical formula of C2H6?
Empirical formula in chemistry refers to a smallest integer ratio of the atoms present in a compound. For example, ethane has molecular formula C2H6. The ratio of number of C atoms to the number of H atoms is 2:6. The simplest integer ratio would be 1:3 and, thus, the empirical formula of ethane is CH3.
What does the empirical formula of a compound describe?
The Empirical Formula An Empirical formula is the chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the actual numbers or arrangement of atoms. This would be the lowest whole number ratio of the elements in the compound.
What is the molecular formula of a compound that has an empirical formula of NO2?
If the molar mass of 138.02 g/mol has been provided for you, divide it by the molar mass of NO2 . Since 3.00 is the whole number, multiply it by the empirical formula. ( NO2 ) × 3.00 = N3O6 is the molecular formula.

How do you convert an empirical formula to a molecular formula?
Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
What is the difference between molecular formula and empirical formula?
Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.
Which of the following can not be an empirical formula for a compound?
Explanation: An empirical formula represents the simplest whole number ratio of elements in a compound. Since the subscripts of the elements in C6H12O6 can be divided by 6 to get the simplest whole number ratio of elements, it is not an empirical formula.
Does C7H14 and C10H20 have the same empirical formula?
The empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. Therefore, the correct answer from the choices is the last option. C7H14 and C10H20 have the same empirical formula which is CH2.
