Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen ! There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole.

Mass of 1 Mole of Water How much water is that to most people? Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.

We find moles of water. All you have to do is just divide 75 by 18 and you'll get 4.17 moles of H2O. That is the final answer.

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. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.

A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Sulfuric acid has the chemical formula H2SO4.

For example, since one atom of oxygen will combine with two atoms of hydrogen to create one molecule of water (H2O), one mole of oxygen (6.022×1023 of O atoms) will combine with two moles of hydrogen (2 × 6.022×1023 of H atoms) to make one mole of H2O.

As one mole of H2 contains 6.022×10^23 molecules of H2. And one molecule contain 2 Hydrogen atoms.

one mole of water contains 6.02 x 1023 MOLECULES of water.

Well 1 mole of water is 2 moles of hydrogen + 1 mole of oxygen - that is; 1.008 x 2, + 16, which is 18.016 grams. Multiply that by the number of moles - 5, so that's 90.08 grams, or about 90mL. There are 90 grams in 5 moles of water.

1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires 100/18 moles of hydrogen. As the molar mass of hydrogen is 2, it requires 200/18 = 100/9 g of hydrogen. It requires 100/9 g of hydrogen gas and 800/9 g of oxygen gas to make 100 g of water.

Thus there are 2.77 moles of hydrogen in 25 g of water.
