The hydrogen molecule is diatomic, H2.
Because each hydrogen molecule contains 2 hydrogen atoms!
The hydrogen molecule is diatomic, H2.
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.
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
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
The scientist who proposed the mole was Avagadro. It is based on his famous number - approximately 6.02 x 1023 .
No. A mole of hydrogen (in its normal form) weighs 2 grams. A mole of water weighs 18 grams.
When 1 mole of hydrogen reacts with 1 mole of chlorine, 2 moles of hydrogen chloride are formed. The molar mass of hydrogen chloride is 36.46 g/mol. Therefore, 2 moles of hydrogen chloride would have a mass of 72.92 grams.
A mole of hydrogen contains Avogadro's number of hydrogen atoms, while a mole of uranium contains Avogadro's number of uranium atoms. Hydrogen is a light element with a low atomic weight, while uranium is a heavy element with a high atomic weight. This means that a mole of hydrogen weighs much less than a mole of uranium.
No, the mole ratio from a balanced chemical equation cannot be directly interpreted as a ratio of masses. The mole ratio represents the ratio of moles of one substance to another in a chemical reaction, whereas the ratio of masses would depend on the molar masses of the substances involved. However, if you know the molar masses of the substances, you can convert between moles and masses using this information.
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
