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.
3.05 x 1025
25x(2/18)=2.78g of hydrogen 25x(16/18)=22.22g of oxygen
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.

45,0 grams of hydrogen gas have 135,5.10e23 atoms.
To determine how many hydrogen atoms are in 301 grams of H2O, we need to consider the molar mass of water (H2O). The molar mass of water is approximately 18 grams/mole. Since the molecular formula of water is H2O, it contains 2 hydrogen atoms. Using this information, we can calculate the number of moles in 301 grams of water and then determine the number of hydrogen atoms present.
To find the number of hydrogen atoms, we need to first determine the number of water molecules in 738 grams of water. Then, using the molecular formula of water (H2O), we know that each water molecule contains 2 hydrogen atoms. Finally, we can calculate the total number of hydrogen atoms by multiplying the number of water molecules by 2.
1,25 grams of CH4 contain 0,156696.10e23 atoms.
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.

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.
There are 4.8 x 10^24 hydrogen atoms in 360 grams of water. This is calculated by using Avogadro's number to convert the mass of water to moles, and then using the chemical formula of water (H2O) to determine the number of hydrogen atoms present in 1 mole of water.
there are 2 atoms of hydrogen in water
