Question

Number of Hydrogen atoms in 1 mole of H2O is:

A. 6.022 x 1023 B. 2 x 6.022 x 1023

C. 3 x 6.022 x 1023 D. 4 x 6.022 x 1023​

Answer 1

Explanation:

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
