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
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.
Methanol is CH3OH, and contains carbon. hydrogen, and oxygen.
Glycerol does not have nitrogen. Chemical formula of it is C3H5(OH)3. It is considered as a tri alcohol.
No, only fatty acids contain carboxyl groups.
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).
Glycerol is CH2OHCHOHCH2OH and so, yesit does contain oxygen.
The common lipids are triglycerides and each contain one molecule of glycerol. Glycerol is a sugar, so the answer is yes.
They all contain glycerol.
Anti Freeze it also has Propylene Glycol.
The triglyceride molecule consists of three lipids bonded one each to the three Carbons of glycerol.
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.
Methanol is CH3OH, and contains carbon. hydrogen, and oxygen.
No, steroids do not contain glycerol. Steroids are a class of organic compounds known for their specific structure and function in the body, while glycerol is a simple sugar alcohol commonly found in lipids and used as a component in various products such as cosmetics and food.
No - neither of them do.
Glycerol does not have nitrogen. Chemical formula of it is C3H5(OH)3. It is considered as a tri alcohol.
No, only fatty acids contain carboxyl groups.
All lipids (fats, oils and waxes) contain fatty acids attached to glycerol.
