# Best answer: How many atoms are in 2 moles of hydrogen?

Contents

2 moles * Avogadros number (atoms/mole) = 1.204*10^(24) atoms. (that is if you mean molecular hydrogen.

## How many atoms are in a mole of hydrogen?

The definition of Avogadro’s number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms.

## How many atoms are in 2 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

## How many atoms are in 2 moles of h2o?

1: Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

## How many atoms of hydrogen are there in 2 moles of NH?

1 mole will have 6.02*10^23 molecules. Therefore 2 moles will have 1.204*10^24 molecules of NH3. There are 4 atoms in each molecule, so 2 moles will have 4*(1.204*10^24) atoms which is 4.816*10^24 atoms.

## How many moles of hydrogen are in H2?

H2 – There are 2 moles of hydrogen atoms (1 mole of elemental hydrogen).

## How many atoms are in a hydrogen molecule H2?

Each hydrogen molecule in hydrogen gas consists of two hydrogen atoms bonded together. Likewise, two oxygen atoms bind to make a oxygen molecule.

## How many moles of hydrogen atoms are present in 2.00 moles of H2O?

1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.

## How many atoms of hydrogen are there?

For every mole, there are 6.02*1023 atoms, so in 1 gram of hydrogen there are 6.02*1023 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unit is TINY.

## How many grams of hydrogen are in 2 moles of water?

If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

## How many water molecules are in 2.00 moles water?

The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
