How many grams of h2 and O2 are produced during electrolysis of water?

Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g) The number of hydrogen molecules produced is thus twice the number of oxygen molecules. Assuming equal temperature and pressure for both gases, the produced hydrogen gas has, therefore, twice the volume of the produced oxygen gas.

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.

How many H2 and O2 are produced if you separate the molecules of water?

The difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen atom, as explained above. This means it takes two water molecules (2 H2O) to make one oxygen molecule (O2). At the same time, however, two molecules of water (2 H2O) can make two molecules of hydrogen (2 H2).

How much oxygen does a liter of water have?

The density of hydrogen and oxygen are 0.0899 and 1.429 g/l at 0 degrees centigrade. One liter of water will thus produce 111/0.0899 =1235 liters of hydrogen and 888.81/1.429 = 622 liters of oxygen.

Why Sulphuric acid is added in electrolysis of water?

Ans :Electrolysis of pure water is very low because water is an covalent compound so it can’t ionize to release ions. To increase the conductivity of water a few drops of sulphuric acid is added .

How do you calculate the weight of water in kg L?

How to Calculate the Weight of Water To find the weight of water, start by finding the density (1 kg/L at 39.2°) and the volume of water. Convert the volume of water to liters and then multiply by the density to find the weight. Use our volume conversion calculators to convert different volumes to liters.

What is the weight of a volume of water?

The weight of a volume of water can be found given the density, which is the mass compared to the volume. The density of water is 1 kilogram per liter (kg/L) at 39.2°. This means that 1 liter (L) of water weighs 1 kilogram (kg) and 1 milliliter (mL) of water weighs 1 gram (g).

How much water is required to produce 1 kg of H2O?

18g of H2O will give 2g of H2 gas so for 1kg of H2 you will need 9000g or 9kg of water. At STP i.e.273K,18g of water gives 1 litre of hydrogen that is about 2g It is assumed that ideal case of electrolysis has occured.

What is the mass of 1kg of H2O + O2?

The method of production of Hydrogen , in here shall be supposed as per the equation 2 H2O —→ 2H2 + O2, a decomposition reaction. A molar ratio can be helpful to determine the mass of obtained product. 1 mol H2O produces 1 mol H2. => 18 g of H2O gives 2g of H2. By unitary method, 1kg of H2 ie 1000g of H2 is 500 mol of the H2 gas.
