Oxygen makes up about 21% of Earth's atmosphere by volume.
Air typically contains about 21% oxygen by volume.
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
The chemical formula for sodium oxide is Na2O. To determine the mass percent of oxygen in Na2O, we need to calculate the molar mass of oxygen (O) and sodium oxide (Na2O), then use these values to calculate the mass percent of oxygen in Na2O.
in one molecule of Fe2O3 there would be 3 oxygen atoms
Silicon dioxide contain 46,743 49 % silicon and 53,256 51 % oxygen.
Air typically contains about 21% oxygen by volume.
33%
Estriol (C18H24O3) contain 16,644 % oxygen.
No.
0%,because it is connected to gutter of delhi
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
There is no answer , -that is an impossible question.
Many acids don't contain oxygen: HF, HCl, HBr, HI, etc.

If a potassium chlorate sample is contaminated with KCl, the experimental percent oxygen would be lower than the theoretical percent oxygen. This is because KCl does not contain oxygen, so the contamination would dilute the amount of oxygen produced during the decomposition of potassium chlorate.
Oxygen does not contain calories because it is not a source of energy for the body.
