how many hydrogen atoms are needed to form 5 water molecules?
538238
Therefore 5 molecules of water have 10 hydrogen atoms. Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen !
946323
In that case a dozen is 12 so 12 × 2 = 24 hydrogen atoms in a dozen water molecules. To get the answers, (4 and 24) you had to multiply the given number of molecules by two atoms of hydrogen per molecule.
464328
There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.
150886
Hydrogen has a molar mass of 1g/mol, so 100 moles of hydrogen atoms are in 100g. As there are two hydrogen atoms per molecule of water, 50 moles of water are produced.
1268545
Each hydrogen atom has 1 proton, no neutrons (assume all H are protonium) and 1 electron. The oxygen atom has 8 protons, 8 neutrons (most abundant isotope) and 8 electrons. Therefore, the water molecule has: 8 + 1 + 1 = 10 protons.

There are two hydrogen atoms in a molecule of water.

But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.
557003
Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.

Therefore, 5 molecules of water is formed when 10 electrons move from mitochondrial NADH molecules through the components of electron transport system to molecular oxyge.

Chemical Formula of Water There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms.

How many molecules of H2O are present in 0.500 mol of water? 1 mol of water contains 6.022 × 1023 H2O molecules Therefore 0.500 mol contains 0.500 × (6.022 × 1023) = 3.01 × 1023 H2O molecules.
456273
Since we know that carbon atoms tend to make four bonds, each carbon atom will have the number of hydrogen atoms that are required for four bonds. This compound contains 16 hydrogen atoms for a molecular formula of C8H16.
177710
As one mole of H2 contains 6.022×10^23 molecules of H2. And one molecule contain 2 Hydrogen atoms. So, 1 mole of H2 will have 1.2044×10^24 atoms.

Part 1. There are 4 moles of hydrogen atoms in 36 grams of water, which is choice a.
807051
There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole. To calculate for 5 moles, (2 H atom)/(H2O molecule) X (6.022x10^23 H2O molecules)/(mole) X 5 moles = 6.022x10^24.

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part.
433136
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Sulfuric acid has the chemical formula H2SO4.
