How many total atoms are in 1.0 moles of H2O ?
There are 6.02 x 10^23 molecules of H2O is 1 mole of H2O molecules. There are two atoms H and 1 atom O in 1 MOLECULE H2O (NOT MOLE); therefore, there are 3 x 6.02 x 10^23 = 18.06 x 10^23 or 1.806 x 10^24 atoms of H + atoms O in 1 mole H2O.
Well, it seems like water is feeling a bit shy these days. In 1.0 mole of H2O, you'll find approximately 1.8 x 10^24 atoms, give or take a few (who's counting, really?). So, there's plenty of microscopic water molecules to go around! Enjoy the wet and wonderful world of chemistry!
To determine the number of atoms in 1.0 mole of H2O, we need to consider the chemical formula of water (H2O), which tells us the stochiometry of the elements present.
In 1 molecule of H2O, there are 2 atoms of hydrogen (H) and 1 atom of oxygen (O). Therefore, 1 molecule of H2O contains a total of 3 atoms.
Avogadro's number states that there are approximately 6.022 x 10^23 entities (atoms, molecules, or formula units) in 1 mole of any substance.
So, in 1 mole of H2O, there are 6.022 x 10^23 molecules of H2O.
To determine the number of atoms, we multiply the number of molecules by the number of atoms per molecule:
Number of atoms in 1 mole of H2O = (6.022 x 10^23) molecules x (3 atoms/molecule)
= 1.8066 x 10^24 atoms
Therefore, there are approximately 1.8066 x 10^24 atoms in 1.0 moles of H2O.
To find the total number of atoms in 1.0 moles of H2O, you need to know two things: Avogadro's number and the molecular formula of water (H2O).
Step 1: Find Avogadro's number
Avogadro's number (symbol: NA) is 6.022 × 10^23. It represents the number of particles (atoms, molecules, or formula units) in one mole of a substance.
Step 2: Determine the molecular formula of water
The molecular formula of water is H2O, which means it contains two hydrogen (H) atoms and one oxygen (O) atom.
Step 3: Calculate the total number of atoms
In 1.0 mole of water, there are 6.022 × 10^23 water molecules. Since each water molecule contains three atoms (two hydrogen atoms and one oxygen atom), you can multiply Avogadro's number by three to find the total number of atoms in 1.0 mole of H2O.
Total number of atoms = Avogadro's number × number of atoms per molecule
Total number of atoms = (6.022 × 10^23) × 3
Therefore, there are approximately 1.807 × 10^24 atoms in 1.0 moles of H2O.
