The C=O groups in and their derivatives are bonded to atoms (oxygen, by lone pairs on the atom adjacent to the p system, eg: -OMe except -R, -Ar or -vinyl 

Oxygen atoms are incorporated in the silicon lattice on an interstitial position (denoted by Oi), where the oxygen atom sits in an almost bond-centered position between two adjacent Si atoms. Several of the local vibration modes are infrared (IR) active. In these respective oxides, for every two atoms of iron, there are two or three atoms of oxygen (Fe 2 O 2 and Fe 2 O 3). As a final example: nitrous oxide is 63.3% nitrogen and 36.7% oxygen, nitric oxide is 44.05% nitrogen and 55.95% oxygen, and nitrogen dioxide is 29.5% nitrogen and 70.5% oxygen. Each molecule only has 1 atom of Oxygen in it, so there are 9.970 * 10^26 atoms of Oxygen in 29.8 L of water. Confirmation that one liter of water has 3.346 * 10^25 molecules is here. How many atoms are in 20g of water?
