1mol O = 16.0g (rounded to 1 decimal place)
1mol O atoms = 6.022 x 1023 atoms
16g O x 1mol/16g = 1mol O
1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
One mole of oxygen has a mass of 16 grams and contains 6.022 x 10^23 oxygen atoms. Therefore, 16 grams of oxygen will also contain 6.022 x 10^23 oxygen atoms.
Just about 16 grams as what you have written in you question is Avogadro's number, which is a mole of anything. Oxygen is 16 grams per mole.
16 grams of oxygen how many moles is 0,5 moles.
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
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.
To find the weight of 4.2x10^24 atoms of oxygen, you need to know the atomic mass of oxygen. The molar mass of oxygen is about 16 grams per mole. So, you can calculate the weight by dividing the number of atoms by Avogadro's number to get the number of moles, and then multiply by the molar mass. In this case, it would be: (4.2x10^24 atoms) / (6.022x10^23 atoms/mol) * 16 grams/mol = approximately 112 grams.
There are 6 moles of oxygen atoms in 2 moles of potassium dichromate (K2Cr2O7). Each mole of K2Cr2O7 contains 7 oxygen atoms, so 2 moles would contain 14 oxygen atoms. The molar mass of oxygen is 16 g/mol, so there would be 224 grams of oxygen in 2 moles of K2Cr2O7.
In potassium dichromate (K2Cr2O7), there are 7 oxygen atoms per molecule. Therefore, two moles of K2Cr2O7 would contain 14 moles of oxygen atoms. Each mole of oxygen atoms has a molar mass of approximately 16 grams, so there would be 224 grams of oxygen in two moles of potassium dichromate.
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
There are 8 carbon atoms and 8 oxygen atoms in 8CO.
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
