What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
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.
What is the mass of 1.0 mole of oxygen?
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.
What weighs more one mole of oxygen or one mole of sodium?
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
What is the mole fraction of oxygen gas in air?
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.
What is a mole cule?
A molecule is a group of two or more atoms held together by chemical bonds. It is the smallest unit of a chemical compound that can exist and retain the compound's properties. Molecules can be made up of the same type of atoms (such as O2) or different types of atoms (such as H2O).
What is the approximate mole fraction of nitrogen and oxygen in the atmosphere combined?
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.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
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.
How many moles of oxygen atoms are present in one half mole of carbon dioxide molecules?
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.
What is the mole ratio of oxygen to pentane?
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.
What is the total number of moles of oxygen atoms in 1 mole of N2O3?
1 mole N2O3 (3 moles O/1 mole N2O3) = 3 moles oxygen atoms ==================
Calculate the number of moles of oxygen atom in 18.1 mole of CH2O?
Since there is only 1 oxygen atom in CH2O, there is the same amount of oxygen atoms as there are molecules of CH2O. So the answer is 18.1 mole. But if you burn it, you will form oxygen in its natural form, which is O2. So there will only be the half the amount of the oxygen. Then the answer would be 18.1 / 2 = 9.05 mole.
