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 of hydrogen are in 2NH3?
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
How many H atoms in 1 mole of C7H16?
There are 16 hydrogen atoms in 1 mole of C7H16.
How many moles are in hydrogen atoms?
divide the mass of the hydrogen by the molar mass.
How many atoms of hydrogen are there in the mole of H2O molecules?
In one mole of water (H2O), there are 2 moles of hydrogen atoms (H) due to the formula H2O having 2 hydrogen atoms. Since 1 mole of hydrogen contains Avogadro's number of atoms (6.022 x 10^23), in a mole of water there are 2 times Avogadro's number of hydrogen atoms, which equals 1.2044 x 10^24 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.
Why one mole of hydrogen molecules and one mole of hydrogen atoms have different masses?
Because each hydrogen molecule contains 2 hydrogen atoms!
How many moles of oxygen are there in one mole of hydrogen peroxide?
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
How many hydrogen atoms are there in 0.5 mole of Hydrogen?
Avagadro's number = 6.022 × 1023 atoms/mol0.5 mol × (6.022 × 1023) atoms/mol = 3.011 ×1023 atoms
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.
How many hydrogen atoms are in 1 mole?
There are approximately 6.022 x 10^23 hydrogen atoms in 1 mole. This number is known as Avogadro's constant.
