Question

calculate the number of hydrogen atoms present in 2 moles of water​

Answer 1

Answer:

1 mole = 6.022×10^23 atoms.

1 water molecule = 2 Hydrogen atoms + 1 oxygen atom.

So, 1 mole H2O = 1.2044×10^24 hydrogen atoms.

Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.

Answer 2

Answer:

12.046×1023  atoms of hydrogen are present in 2 moles of hydrogen atoms.

Explanation:

• 18 g of water make up the bulk.
• By multiplying the number of atoms by the atomic number and adding the atoms' atomic weights, one may determine the molecular weight.
• Hydrogen has an atomic weight of 1.
• Oxygen has an atomic weight of 16.
• No. of moles = 2
• 1 mole of water = 6.023×10²³ atoms
• 2 moles of water = 2×6.023×10²³ atoms = 12.046×1023  atoms of hydrogen.
