Frequently asked questions
What is the molar mass of C20H28O2?
The molar mass of C20H28O2 is 300.44 g/mol, calculated from standard atomic weights for 20 carbon atoms, 28 hydrogen atoms and 2 oxygen atoms. The monoisotopic mass is 306.2466 Da.
How many compounds have the formula C20H28O2?
CompoundList lists 188 compounds with the molecular formula C20H28O2, including alpha-Retinoic acid, (7alpha,17beta)-3-Methoxy-7-methyl-estra-1,3,5(10)-trien-17-ol, 3-Methoxy-7-methylestra-2,5(10)-dien-17-one. Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of C20H28O2?
C20H28O2 has a degree of unsaturation of 7. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
