hydrogen is H2, with a molecuar weight of 2.016. In 1.008 grams of H2 there are 3.011 X 10 raised to power 23 (approx) 2.011 X 1023 molecules or 6.022 X 1023 atoms. Ovviously you can go straight to the answer as the weight is the Atomic Mass in grams.

5.839 grams C8H8 ( 1 mole C8H8/104.144 grams)(8 mole H/1 mole C8H8)(6.022 X 1023/1 mole H) = 2.701 X 1023 atoms of hydrogen --------------------------------------------
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
The % of hydrogen is superfluous information 1.5 lb H2O2 (454 grams/1 lb)(1 mole H2O2/34.016 grams)(2 mole H/1 mole H2O2)(6.022 X 10^23/1 mole H) = 2.4 X 10^25 atoms of hydrogen
None. Hydrogen is an element. It contains only hydrogen atoms.
Five(5) hydrogen atoms
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
1,204428358.1023 atoms of hydrogen
There are 1000 grams in one kilogram. Therefore, 1008 grams is equal to 1008/1000 = 1.008 kilograms.
1,25 grams of CH4 contain 0,156696.10e23 atoms.

6.6x1022 per gram of water
5.839 grams C8H8 ( 1 mole C8H8/104.144 grams)(8 mole H/1 mole C8H8)(6.022 X 1023/1 mole H) = 2.701 X 1023 atoms of hydrogen --------------------------------------------
31 grams CH2O (1 mole CH2O/30.026 grams)(2 mole H/1 mole CH2O)(6.022 X 1023/1 mole H) = 1.2 X 1024 atoms of hydrogen =======================
So, there are approximately 8.74 × 1 0 24 8.74×10 24 hydrogen atoms in 800 grams of C 3 H 8 C 3 H 8 .
1 Mol of Hydrogen has a mass of 1.0078 grams (g) 1 Hydrogen molecule is 1.673 X 10-24 grams(g) Therefore, if you know how Mols of Hydrogen there are in a solution then you can calculate the number of hydrogen molecules as follows: Example: A Solution has 5 Mols of Hydrogen, How many Hydrogen molecules are there in the solution? answer: 5 X (1.0078g) / 1.673 X 10-24 grams(g) = 3.01 X 1024 atoms
