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 molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
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.
What is the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure?
The ratio of the average velocity of hydrogen molecules to neon atoms is the square root of the ratio of their molar masses. Since the molar mass of neon is about 20 times that of hydrogen, the average velocity of hydrogen molecules would be about √20 times faster than that of neon atoms.
How many atoms are in five molecules of hydrogen?
ten as each hydrogen molecules contains two 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
Are atoms of the same element but with different masses are called ions?
No, atoms of the same element but with different masses are called isotopes. Ions are atoms or molecules that have gained or lost electrons, resulting in a net electric charge.
Do hydrocarbon molecules always contain hydrogen carbon and oxygen atoms?
No.Hydrocarbon molecules contain hydrogen and carbon atoms.It is carbohydrate molecules that contain hydrogen, carbon, and oxygen atoms.
Are hydrogen atoms in water molecules identical to all other hydrogen atoms?
Yes, hydrogen atoms in water molecules are identical to each other in terms of their chemical properties and behavior. However, due to their location in the molecule, they may have slightly different electronic environments.
How many hydrogen atoms are found in 2 molecules of hydroxylamine?
The formula of hydroxylamine is HONH2, showing three hydrogen atom per molecule. Therefore, in 2 molecules there will be six hydrogen atoms.
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
How are elements atoms and molecules are related?
Atoms are elements , e.g Hydrogen. Molecules are combinations of atoms, e.g water H2O is the combination of Hydrogen and Qxygen.
If two atoms of nitrogen completely react with six atoms of hydrogen to form two molecules of ammonia which best describes the number of hydrogen atoms present in the two molecules of ammonia?
Two molecules of ammonia contain 6 hydrogen atoms.
