What is the mass in grams of one mole of hydrogen atoms?

An amount of any substance in grams that is numerically equal to its atomic or molecular weight in amu has been defined as one mole of that substance. By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams.

Therefore, The weight of atom of Hydrogen is. 66058 × 10 – 24 grams .

Therefore, The weight of atom of Hydrogen is. 66058 × 10 – 24 grams .

A. 1 mole of hydrogen (H) atom Contains 6.023 X 10²³ Atoms of hydrogen. The atomic mass of a hydrogen atom is 1.008 grams. So, in terms of the mole concept, we can infer that 1 mole of hydrogen atoms= 1.008 grams hydrogen=6.023 X 10²³ Atoms of hydrogen.

The mass of one mole of a hydrogen atom is 1 gram, whereas the mass of one mole of hydrogen molecules is 2 grams. One mole of hydrogen molecule has a mass of 2 grams because hydrogen molecules are formed by binding two hydrogen atoms.

Since hydrogen is a diatomic molecule, its atoms are found in pairs. ∴ 3. 02 × 1023 molecules Are present in one gram or one mole of hydrogen.

Hydrogen is the chemical element with the symbol H and atomic number 1. At standard conditions, hydrogen is a gas of diatomic molecules having the formula H₂.

What is Hydrogen (H₂)?

The mass of 1-mole atoms of an element expressed in grams is called its Gram atomic mass. For example, the gram atomic mass of Na is 23g. The mass of 1 mole of a compound expressed in grams is called its gram molecular mass or molar mass. It is represented by M and expressed as g/mol.

The molar mass of H2 is 2 g/mol. Thus 1 mole of H2 = 2 grams. 3 moles of H2 =3×2=6.

For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 10²³ Hydrogen atoms.

Hydrogen is a diatomic element and therefore it will contain two atoms while helium is a monatomic element and thus it will contain one atom only. Two atoms of hydrogen mean, it will have one number of moles and as helium is monoatomic. So, it will have only one 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).

One gram of hydrogen contains 1 mole of hydrogen As its atomic weight is 1. 1 mole =6. 023×1023 atoms. But, hydrogen is diatomic molecule. So, its atom are found in pairs.

Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unit is TINY. One gram is equal to about 602000000000000000000000 amu (or 6 followed by 23 zeros). So, because the mass of hydrogen is close to 1 amu (atomic mass unit),1 gram of hydrogen contains about that same huge number of atoms.

∴3. 02×1023 Molecules are present in one gram of hydrogen.

A gram is a unit of mass in the metric system defined as One thousandth (1 x 10^–3) of a kilogram. Originally, the gram was defined as a unit equal to the mass of one cubic centimeter of pure water at 4°C (the temperature at which water has maximum density).

Gram atomic mass of Hydrogen =1 g. Gram atomic mass of Oxygen =16 g.
