Respuesta :

C6H12 is its molecular formula.

What is molecular formula?

Two or more atoms that have been chemically bonded make up a molecule. A molecular formula is the chemical representation of a molecular compound that lists the types and quantities of atoms that make up each molecular unit.

% Carbon equals 85.63%.

Hydrogen percentage:

100% - 85.63% = 14.37%

84.16 g/mol for molar mass

Molecular formula is: =?

% should be treated as mass (g) and their atomic mass divided.

C = 85.63 / 12 = 7.14

H = 14.37 / 1 = 14.37

Subtract the smallest number from both.

C = 7.14 / 7.14 = 1

H = 14.37 / 7.14 = 2.01

, CH2 is the empirical formula.

Empirical weight is equal to 12 + 2 = 14.

n = Molecular weight/Empirical weight

n = 84.16 / 14 = 6.01

Empirical formula times n yields the molecular formula.

Now,

C6H12 = (CH2)n = (CH2)6
