How many hydrogen can be extract from 1 liter water?

Answer 1

Liquid hydrogen (LH2) tanks can store more hydrogen in a given volume than compressed gas tanks. The volumetric capacity of liquid hydrogen is 0.070 kg/L, compared to 0.030 kg/L for 10,000-psi gas tanks

Answer 2

As we know that in 22.4lt there is one mole of any gaseous molecules.

Hence in water there are avogadro no.(N) of molecules of water and in each of them are two hydrogen atoms so

No. of hydrogen atoms in 22.4lt = 2 X N

so No. of hydrogen atoms in 1lt water = (2 X N)/22.4

Answer 3

1 liter water has a mass of about 1 kilogram, and water consists of 1/9 hydrogen (and 8/9 oxygen) by weight, so you'll get about 1/9 kilogram of hydrogen.

1 mole of water is 18 grams, 1 kilogram of water is 55.5556 moles of water (1000 g/18 g).

1 mole of water would yield 1 mole of H2.

1 litre of water would yield 55.5556 moles of hydrogen, at standard conditions that is 1250 litres, or 1.25 metre3.

Answer 4

Assuming STP:

1 Liter of H2O = 1 kg of H2O = 1000 g of H2O

Using Atomic Mass

H: 1.00794 grams per mole

O: 15.9994 grams per mole

H2O: 18.01528 grams per mole

1000 / 18.01528 = 55.5084 moles of H2O

H2O -> H2 + 1/2 O2

This means we have 55.5084 moles of H2

The volume of a mole of gas is 22.41 L

22.41 L/mol * 55.5084 mol = 1243.944

You can get about 1244 liters of hydrogen gas from one liter of water.
