I Wish I Was a Mole in the Ground was created in 1924.
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
The molar mass of oxygen is approximately 16.00 grams per mole. Therefore, the mass of 1.0 mole of oxygen is 16.00 grams.
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.

The mole ratio of oxygen to pentane in the balanced chemical equation for the combustion of pentane is 13:1. This means that 13 moles of oxygen are required to completely react with 1 mole of pentane.
1 mole N2O3 (3 moles O/1 mole N2O3) = 3 moles oxygen atoms ==================
