aGiven the atom and mass ratios of X to oxygen, you need to figure out the mass of X that combines with 47.998 u O, i.e., the mass of three O atoms. At this point you divide by 2 and the result should appear some place in the periodic table! 假使X原子和大量比率氧气,您需要推测...

If the atomic mass of an element is X, what is the mass in grams of 6.02 times 10^{23} atoms of the element? If 3 moles of an element have a mass of 222.0 g, what is the mass of 1 atom? Typically, the mass of an atom of an element in grams is closest to: a. 1023 b. ...
benzoyl unit, and hexose moiety. M17and M18were deduced as benzoyloxypaeoniflorin and its isomer. M19displayed the [M−H]−ion atm/z583.18210 (C30H31O12), which had one less oxygen than that of M17and M18. By comparing and the analysis of their MS/MS spectra, the absence of ion ...
Compared the structure of PBDEs and eBFRs, it is clear that the existence of oxygen atom in PBDEs can provide lone pair electrons and proton transfer ions are tend to produced. Furthermore, the presence of modifiers leads to remarkable decreasing of the M+· intensity. Thus, the whole ...

It looks like each cellulose molecule has 5 Oxygen atoms and 1 Carbon atom and some bits of Hydrogen. Oxygen has a higher atomic weight than carbon so I think the mass of a tree is mostly Oxygen. This makes sense because when I go camping and burn tree parts, what is left in...
The latter (linoleate:oxygen oxidoreductase, EC 1.13.11.12) belongs to the family of lipoxygenases, enzymes widely distributed in plants and animals, known to catalyze the regio- and stereo-specific hydroperoxylation of polyenoic fatty acids containing a (1Z, 4Z)-pentadiene or a (1Z, 4Z, 7Z...
