formula of ethylene glycol is C2H6O2
ie CH2OH-CH2OH
approximate atomic masses of C=12
H=1
O=16
therefore,
2*12+6*1+2*16
= 24+6+32
=62g/mol

1. Product Identification
from the website: http://www.jtbaker.com/msds/englishhtml/e5125.htm
Synonyms: 1,2-Ethanediol; glycol; 1,2-Dihydroxyethane; Ethylene Alcohol; Ethulene Dihydrate
CAS No.: 107-21-1
Molecular Weight: 62.07
Chemical Formula: CH2OHCH2OH
Product Codes:
J.T. Baker: 5387, 5845, 9140, 9298, 9300, 9346, 9356, L715
Mallinckrodt: 5001, 5037
to figure it out yourself, use the formula and count the atoms:
carbons - 2
hydrogens - 6
oxygens - 2
now look up the weight of each of these atoms in a handy periodic table of the elements C = 12.011 H = 1.0079
O = 15.9994
Do the arithmetic you get 62.068 which matches the 62.07 above.

The molecule is HO-HCH-HCH-OH or C2H6O2
2 C gives 2 x 12 gram
6 H gives 6 x 01 gram
2 O gives 2 x 16 gram
Together is 62 gram. This the molecular mass.

Just have a proper diet rich in fiber and protein and try to cut all the unhealthy stuff from your diet atlhough its good to enjoy. Dont binge on unhealthy stuff any other time. You should also exercise 3-5 times a week and you should definitely see results in a couple of weeks. Learn more here:

Take the all seperate elements (ie Carbon, Oxygen, Hydrogen) and multiply the total amount of that element by that elements atomic weight, add them all together.

you need to find the molar weight of the molecule.. each atom in the molecule has a different weight and you need to find the mass of each one of those atoms and combine them all ....
