H2OCount two atoms hydrogen in one molecule of water.
I assume you mean 0.5 grams water. 0.5 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 10^23/1 mole H) = 3.3 X 10^22 atoms of hydrogen
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
6.6x1022 per gram of water
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
1,204428358.1023 atoms of hydrogen
1,25 grams of CH4 contain 0,156696.10e23 atoms.
2 hydrogen atoms per molecule of water.
there are 2 atoms of hydrogen in water

1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================
H2OCount two atoms hydrogen in one molecule of water.
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
Quite a few! 738 grams water (1 mole H2O/18.016 grams)(2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H) = 4.93 X 10^25 atoms of hydrogen
