How do you find the empirical formula?
Calculate the empirical formula.
- In any empirical formula problem you must first find the mass % of the elements in the compound.
- Then change the % to grams.
- Next, divide all the masses by their respective molar masses.
- Pick the smallest answer of moles and divide all figures by that.
Which is the empirical formula for ethylene glycol?
The empirical formula of ethylene glycol is CH 3 O. To find the empirical formula, we begin with the molecular formula for ethylene glycol, C 2 H 6 O 2 …. See full answer below. Our experts can answer your tough homework and study questions.
Which is the simplest member of the glycol family?
Ethylene glycol, also known as ethane-1,2-diol, is the simplest member of the organic compound family glycol. A glycol is an alcohol on adjacent carbon atoms, with two hydroxyl groups. The common name ethylene glycol simply means “ethylene derived glycol.”
Why is the structure of ethylene glycol polar?
First, ethylene glycol comprises polar O-H groups; they are polar since oxygen is much more electronegative than hydrogen, and thus appears to polarize the pair of electrons in the O-H bond. To know more about the production, uses, and structure of Ethylene Glycol (C 2 H 6 O 2) register now.
Where does ethylene glycol come from and how is it made?
Ethylene glycol has been synthesized by the oxidation of ethylene with O 2 to ethylene oxide and the subsequent hydration of ethylene oxide to ethylene glycol. Usually, ethylene is supplied from the thermal cracking of naptha from petroleum refining.
What is the chemical formula for ethylene?

What is the molecular weight of ethylene glycol?
The average molar mass of the chemical compound Ethylene glycol is 62.070 grams per mole
Is ethylene glycol soluble in water?
Glycerol and ethylene glycol are most definitely soluble in water. They have a high hydroxyl/carbon ratio which makes them very polar and are very soluble in other protic solvents (ones that can hydrogen bond) such as water. Antifreeze is actually a mixture of glycol and water,…
