Explain a molecular formula twice its empirical formula

Reference no: EM13264468

A 1.678 g sample of a component of the light petroleum distillate called naphtha is found to yield 5.143 g CO2 (g) and 2.456 g H2O (l) on complete combustion. This particular compound is also found to be an alkane with one methyl group attached to a longer carbon chain and to have a molecular formula twice its empirical formula.

The compound also has the following properties:

melting point of -154 C ,

boiling point of 60.3 C ,

density of 0.6532 g/mL at 20 C ,

specific heat of 2.25 J/(g*C), and

-204.6 kJ/mol

Use the masses of carbon dioxide, CO2, and water, H2O , to determine the empirical formula of the alkane component.
