Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
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!
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 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.
How many hydrogen atoms are in 1 kg?
Since we know the grams, 1kg or 1000g, we simply divide by the molar mass (1.0079g/mole) to get 992.2 moles of hydrogen. We then multiply by Avagadro's number, 6.0221415x1023. This gives us 5.975x1026 atoms in a 1kg sample of hydrogen.
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
Is a 16.00-g sample of oxygen atoms contains the same number of particles as a 4.003-g sample of He atoms?
Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.
Avogadro's number of aluminum atoms has a mass equal to?
Thast is one mole. 26.98 grams/per mole is the mass.
