Frequently asked questions
What is the molar mass of C21H30O3?
The molar mass of C21H30O3 is 330.47 g/mol, calculated from standard atomic weights for 21 carbon atoms, 30 hydrogen atoms and 3 oxygen atoms. The monoisotopic mass is 339.2760 Da.
How many compounds have the formula C21H30O3?
CompoundList lists 202 compounds with the molecular formula C21H30O3, including 17alpha-Hydroxypregn-4-ene-3,20-dione, 17-beta-Hydroxy-5alpha-androst-1-en-3-one acetate, Pregnane-3,6,20-trione. 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 C21H30O3?
C21H30O3 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.
