593 g H2O x 1 mol/18 g x 2 mole H/mole H2O x6.02x10^23 H atoms/mole H = 4x10^25 atoms of H
6.6x1022 per gram of water
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
1,204428358.1023 atoms of hydrogen
3.05 x 1025
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 ========================
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.
3.05 x 1025
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
there are 2 atoms of hydrogen in water
2 hydrogen atoms per molecule of water.
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 ========================
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.
H2OCount two atoms hydrogen in one molecule of water.
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
