The chemical equation for complete burning of octane is:
2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O.
This equation shows that 25 moles of diatomic oxygen are required to completely burn each two moles of octane. The gram molecular mass of octane is 114.23 and the gram molecular mass of diatomic oxygen is 2(15.9994). Therefore, the ratio of the mass of oxygen required to completely burn any given mass of octane to the mass of the octane to be burned is 50(15.9994)/2(114.23) or 3.5016, to the justified number of significant digits (the same as the number of digits in the least precisely specified datum 114.23, and the mass of oxygen required to burn 19.8 g of octane is (3.5016)(19.8) or 69.3 grams to the justified number of significant digits, now limited by the less precisely specified datum 119.8.
actually compressed oxygen does actually have weight.
an oxygen and a hydrogen atom do not weight the same
As per the modified periodic table, the fourth element after oxygen considering their atomic weights is Ca and thus if the atomic weight of oxygen is considered to be as 16, therefore the atomic weight of Ca is 20
because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.
Oxygen is a non metal element. Atomic number of it is 8.

The atomic weight of oxygen is 15.9994

Three atoms of oxygen are required to react with each two atoms of aluminum to form the most common product of reaction between oxygen and aluminum. Therefore, 0.75 mole of oxygen atoms will be required to react with 0.5 mole of aluminum atoms. The atomic weight of oxygen is 15.999; therefore, the mass will be (0.75)(15.999) = 12 grams of oxygen, to the maximum possibly justified number of significant digits.
The atomic weight of oxygen is 15,999.

Oxygen
One litre of 93 Octane fuel weighs about 6.35 lbs. This weight may vary depending on the temperature, type and blend of the fuel.
well according to my calculations !!OINK OINK !!oxygen has no weight it is free living !!!!
Oxygen comprises about 47% by weight of Earth's crust
The atomic mass of Oxygen is 15.9994.
