Hydrogen has an Atomic Mass of 1.00794 or 1.
What else can I help you with?
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
One mole of hydrogen molecules (H2) contains 2 hydrogen atoms per molecule, while one mole of hydrogen atoms contains single hydrogen atoms. Since the mass of a hydrogen atom is approximately half the mass of a hydrogen molecule, the molar mass of hydrogen molecules is higher than the molar mass of hydrogen atoms.
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
What is the method of working out the molecular mass of hydrogen?
On the periodic table it says that one mole of hydrogen atoms weighs 1.008 grams. However, Hydrogen is a diatomic molecule (it is composed of two hydrogen atoms in its molecular state). Hence, the molecular mass of hydrogen is 1.008 multiplied by 2 = 2.016g this is the mass of one mole of hydrogen. Hope this helps!
Is there such thing as 6.0221023 atoms equal to 1g?
Yes. One mole (6.022x1023) of hydrogen atoms would have a mass of about 1g.
Why one mole of hydrogen molecules and one mole of hydrogen atoms have different masses?
Because each hydrogen molecule contains 2 hydrogen atoms!
Why one mole of hydrogen molecule and 1 mole of hydrogen atoms have different masses?
1 mol of hydrogen molecule = 1 mol of H2 = molar mass of H2 = 2.0gmol-1 2.0gmol-1 x 1mol = 2.0g 1 mol of hydrogen atom = 1 mol of H = molar mass of H = 1.0gmol-1 1.0gmol-1 x 1mol = 1.0g Hence, they have different masses
What is one mole of hydrogen atom?
well firstly its got nothing to do with that its hydrogen so i guess its no!! One mole of hydrogen contains 6.022 x 1023 atoms of hydrogen and weights 1 gram. The hydrogen will exists in the molecular [H2] and so there will be 3.011 x 1023 molecules of hydrogen.
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
What weighs more hydrogen atoms or carbon atoms?
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
How many atoms are in 1.0 g of hydrogen atoms each of mass 1.0amu?
1 gram is 1 mole of hydrogen because the molecular weight is 1. so. 1 mole contains 6.022x10^23 molecules according to avagadro's law. 1amu cannot be directly related to molecule number as far as i am aware
What is the relationship between an Atoms mass and one mole of that atom?
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
