How many atoms of hydrogen are in H2?
two atoms
There are two atoms in hydrogen. The molecular formula of hydrogen is H2, which means one molecule of hydrogen has two atoms.
How many hydrogen atoms H are there in one mole of water H2O?
Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.
How many total atoms are in H?
H : There’s 3+1=4 atoms of hydrogen without the coefficient (it appears once as H3 and once as H ), so there’s 4×5=20 atoms of hydrogen with the coefficient. O : 2×5=10 atoms.
What is Avogadro’s number how many hydrogen atoms are there in 1 mole of water molecule H2O?
6.022 x 1023 hydrogen atoms represent one mole of hydrogen. 6.022 x 1023 water molecules represent one mole of water. 6.022 x 1023 elephants represent one mole of elephants. Take this reaction as an example: NaOH + HCl = NaCl + H2O.
Is H2 one or two moles?
Correct answer: The question indicates that there is 1 mole of H2. Thus there are 6.022 * 1023 molecules of H2. However the question is asking for the amount of atoms in 1 mole of H2. Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule.

How many atoms are there in 1 mole of h2o?
one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.
How many liters are in 1 mole of H2O?
One mole of water has a mass of 18 grams and volume of 18 milliliters or 0.018 liters.
