90 g water: 5 moles
6,4 g methanol: 0,2 mol
18,4 g glycerol; 0,2 mol
Total number of moles: 5,4
Mole fraction of glycerol: 0,2/5,4=0,037

n H2O 90/18:- 5
n CH3OH 6.4/32:- 0.2
n glycerol 18.4/92:- 0.2
add all no. of miles:- 5+0.2+0.2:- 5.4
Mole fraction of glycerol:- 0.2/5.4:- 1/27

What elements does methanol contain?
Methanol is CH3OH, and contains carbon. hydrogen, and oxygen.
Are lipids composed of fatty acids and glycerol?
No, Lipids only contain carbon, hydrogen and oxygen
Is a mixture of water and glycerol homogeneous?
Glycerin is another name for glycerol, which is a pure compound, not a mixture. However, if you leave pure glycerol exposed to the air, it will attract moisture, so an opened bottle labeled "glycerin" may in fact contain a mixture of glycerol and water (up to about 20% water).
Do fatty acid and glycerol both contain a carboxyl group?
No, only fatty acids contain carboxyl groups.
What is a aqueous solution?
An aqueous solution contain a solute dissolved in water.
Does a Sphingomyelin contain glycerol?
No
Do steroids contain glycerol?
no
What elements does methanol contain?
Methanol is CH3OH, and contains carbon. hydrogen, and oxygen.
Is oxygen found in glycerol?
Glycerol is CH2OHCHOHCH2OH and so, yesit does contain oxygen.
Do lipids contain sugar?
The common lipids are triglycerides and each contain one molecule of glycerol. Glycerol is a sugar, so the answer is yes.
What foods contain glycerol?
Glycerol is contained in a variety of sweet foods. You can find Glycerol in marshmallows, puddings, yogurt, and condensed milk.
What do oils fats and waxes all contain?
They all contain glycerol.
What household items have methanol in them?
Anti Freeze it also has Propylene Glycol.
Do fatty acids and glycerol both contain an amino group?
No - neither of them do.
Is glycerol suitable for vegetarians?
Generally no, as most products containing Glycerol originate as a by-product of soaps and body lotions, which the majority of contain animal fats. However, Glycerol in itself comes from plants, so this may alter the answer to your question depending on what the Glycerol is mixed with.
What molecules are the building blocks of fats?
All lipids (fats, oils and waxes) contain fatty acids attached to glycerol.
How many fatty acids and glycerol do triglycerides contain?
The triglyceride molecule consists of three lipids bonded one each to the three Carbons of glycerol.
