Answer:
2.0158 grams
Explantion:
We are to find the mass of the hydrogen atoms in 1 mole of water.
We know that the formula of water is: [tex] H_2O [/tex]
We can see, from the above mentioned formula, that water has 2 hydrpgen atoms.
From the periodic table, we get to know that Hydrogen has an atomic mass of 1.00794 grams.
As there are 2 atoms of hydrogen in water so [tex]2 \times 1.00794 = 2.0158[/tex] grams is the answer
