How much water do you need to make 1kg of hydrogen?
about 2.4 gallons
Based on the atomic properties of water, 1 kg of hydrogen gas requires about 2.4 gallons of water as feedstock. In one year, 60 billion kilograms of hydrogen would require 143 billion gallons of fresh, distilled water.
What is the percentage of hydrogen in water?
11.11\%
The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is 11.11\% and the mass percent oxygen is 88.89\%.
How much hydrogen is in a liter of water?
In one liter of water, there is about 111.11 gr Hydrogen with the volume of 1.33 m3, and 888.8 gr of Oxygen and it’s volume is 0.670 m3!
How many grams of hydrogen are in H2O?
Thus the total atomic mass of H2O is 18. Therefore. hydrogen is 2/18ths of the atomic mass of H2O. 2/18th of 36 is 4, so the answer is 4 grams.
What amount of H2O will be produced by 1 gram of hydrogen?
So 8 g of oxygen will react with 1 g of hydrogen to produce 9 g of water.
How many hydrogen atoms are in a liter of water?
2 hydrogen atoms
A liter of water is 1000 cubic centimeters. Water is easy because each cubic centimeter has 1 gram of mass. Water is made up of 2 hydrogen atoms and one oxygen atom. Hydrogen has an atomic weight of 1 and oxygen has an atomic weight of 16.
How much water does it take to make 1kg of hydrogen?
Based on the atomic properties of water, 1 kg of hydrogen gas requires about 2.4 gallons of water as feedstock. In one year, 60 billion kilograms of hydrogen would require 143 billion gallons of fresh, distilled water. How many Litres is 1kg of hydrogen?
How many megajoules are in a kWh of hydrogen?
A fuel cell that is 60\% efficient requires 1.666 kWh of chemical energy to generate 1 kWh of electrical energy. Now a kWh equals 3.6 megajoules. A kilogram of hydrogen contains 141.8 megajoules.
How much does it cost to produce hydrogen?
Source cost: $1.50 per 1000/gal. or $0.0015/gallon 2. Refinery Costs: $700 – $3,500/bpd. Miles per kg of Hydrogen: 81. Additional Environmental Impact Costs: No. Foot Notes: 1. Hydrogen is measured by the kilogram. 1 kilogram is 1 gallon of gasoline equivalent (gge).
How many grams of hydrogen are in one litre of hydrogen gas?
1 litre of hydrogen gas at STP is 1/22.4 mol. 1 mol of hydrogen is 2 grams. So that’s 89.2857 milligrams of hydrogen. At 100 bar one litre stores 8.92857 grams at standard temperature.
