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.
10 moles of oxygen atoms or 5 moles of oxygen 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.
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
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
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.
There is 1 Avagadro number - so, 6.022 x 1023 molecules in 1 mole of oxygen.
how many atoms, molecules and ions are present in one mole of a substance
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.
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
10 moles of oxygen atoms or 5 moles of oxygen molecules.
There are 2 hydrogen atoms and 1 oxygen.
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.
48.0 g O2 x 1 mole O2/32 g x 6.02x10^23 molecules O2/mole O2 = 9.03x10^23 molecules of O2
There are 1/6.022 x 1023 = 1.66 x 10-24 moles of oxygen in 1 molecule of O2.
1 mole of O atoms, or 0.5 moles of o2 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.
