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.
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 in 1 mole of water?
There ia 6.02 x 10^23 molecules of water in one mole of water. There are three atoms in one molecule of H2O (two hydrogen and one oxygen) So there are 18.12x10^23 atoms in a mole of water molecules
What is the total number of moles of hydrogen in 1 mole of NH4 2HPO4?
In NH4 2HPO4, there are 4 moles of hydrogen atoms present. Since each mole of hydrogen molecule (H2) contains 2 moles of hydrogen atoms, there are a total of 2 moles of hydrogen molecules in 1 mole of NH4 2HPO4.
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 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.
How many atoms of hydrogen are in 2NH3?
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
Why one mole of hydrogen molecules and one mole of H-atoms have different masses?
The hydrogen molecule is diatomic, H2.
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.
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 is the avogadros number related to the mole?
Avogadro's number (generally written as 6.02 x 10^23) is the number of atoms or molecules it takes to have one mole of a particular atom or molecule. For example, one mole of Hydrogen is just 6.02 x 10^23 atoms of hydrogen.
Why the number of atoms in one mole of hydrogen is double the number of atoms?
Because hydrogen occurs in nature as the diatomic molecule H2. So every molecule of H2 contains two hydrogen atoms. 1 mole of H2 has 6.022 x 1023 molecules of H2, while the number of atoms is twice that at 1.204 x 1024 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 hydrogen atoms are there in 3.50 grams of methane?
3.5 g CH4 x 1 mole/16 g x 6.02x10^23 molecules/mole x 4 H atoms/molecule = answer.
How many atoms in 1 mole of water?
There ia 6.02 x 10^23 molecules of water in one mole of water. There are three atoms in one molecule of H2O (two hydrogen and one oxygen) So there are 18.12x10^23 atoms in a mole of water molecules
