The number of any item in a mole is equal to Avogadro's number, or 6.0221415 × 10^23 items. So, in the case of O2, it would be 6.0221415 × 10^23 O2 molecules. It's like asking how many eggs in a dozen versus how many marbles in a dozen, no matter what you're talking about, a dozen is 12. Same thing for moles.

How many oxygen molecules are in 9.1 L of oxygen gas at STP?
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
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.
How many moles of oxygen are in one mole of P4O10?
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
How many atoms of oxygen are in 300 molecules of CH3CO2H?
CH3CO2HIn one molecule, there is 2 atoms of oxygen. So, in 300 molecules, there will be 600 oxygen atoms.
How many moles are equal to 3.6 x10 to the 23 power molecules of oxygen gas O2?
One mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes.So you multiply 23 with 6.02 × 1023 to get 1.38 × 1025
How many molecules are there in one mole of oxygen?
There is 1 Avagadro number - so, 6.022 x 1023 molecules in 1 mole of oxygen.
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.
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 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.
How many molecules in oxygen gas?
There are 1/6.022 x 1023 = 1.66 x 10-24 moles of oxygen in 1 molecule of O2.
What is mass of one mole of oxygen molecule?
The molar mass of oxygen is approximately 16 grams per mole. This means that one mole of oxygen molecules (O2) would have a mass of 32 grams, since each molecule of O2 consists of 2 oxygen atoms.
How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
Why does 1mole of oxygen atoms contain the same number of atoms as 0.5 moles of O2 molecules?
1 mole O vs 0.5 mole O2 A mole of anything is 6.022 X 10^23, Avogadro's number. So one mole of single oxygen atoms is Avogadro's number while 1/2 mole of one oxygen atom is 3.011 X 10^23. So you have 1/2 mole of two oxygen atoms. 3.011 X 10^23 + 3.011 X 10^23 = 6.022 X 10^23
What is the relationship between a mole of oxygen and a mole of hydrogen in terms of their respective quantities and atomic composition?
A mole of oxygen and a mole of hydrogen have the same quantity of particles, which is approximately 6.022 x 1023 atoms or molecules. However, they differ in their atomic composition, with oxygen having 16 times the atomic mass of hydrogen.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
What does 16.0 grams of oxygen contains?
1 mole of O atoms, or 0.5 moles of o2 molecules.
Which term is same for one mole of oxygen and water?
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
