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.
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
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.
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.
CH3CO2HIn one molecule, there is 2 atoms of oxygen. So, in 300 molecules, there will be 600 oxygen atoms.
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
There is 1 Avagadro number - so, 6.022 x 1023 molecules in 1 mole of oxygen.
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.
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 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.
There are 1/6.022 x 1023 = 1.66 x 10-24 moles of oxygen in 1 molecule of O2.
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.
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
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
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.
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.
1 mole of O atoms, or 0.5 moles of o2 molecules.
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
