We are to find the mass of the hydrogen atoms in 1 mole of water.
We know that the formula of water is: 
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
grams is the answer
Maybe molecules one electron
Answer:
the answer is not d because you can pee without moving. so its a because without the food nutrient no part of our body can work
N2<span> + 3H</span>2<span> = 2NH</span><span>3
so, NH3 = (N2 + 3H2)/ 2
= (28g + 3*25g)/2
= 51.5g</span>
Testable, that is always required for a hypothesis. Otherwise, how can you prove it?
