## How many atoms are there in 1 mole of oxygen?

1.4.

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms.

## What is the number of atoms in 1 mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How much oxygen is in a mol?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## Which of the following is correct for 1 mole methane?

One mole of methane specifies NA , Avogadro’s number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .

## How many atoms of hydrogen are in 1 mole of water h20 )?

In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.
