Well a mole of Hydrogen weighs 2.02 grams (two hydrogen atoms at 1.01g each) and at 25ºC a mole of ideal gas (a mole of any gas contains 6.022 * 10^23 molecules - a fixed quantity known as Avagadro's number or constant) and occupies 22.47 litres at 1 atmos. pressure. Therefore 1 litre of H2 at 1 atmos. pressure and 25ºC weighs 2.02/22.47 grams.
Hydrogen gas is typically weighed using a scale that measures the mass of the container holding the gas. The container needs to be completely sealed to prevent the hydrogen from escaping. The difference in weight before and after adding the hydrogen gas gives the weight of the hydrogen.

How much is 500 cc's of hydrogen peroxide?
500 cc's of hydrogen peroxide is equivalent to 500 milliliters. Hydrogen peroxide has a density of 1.5 g/ml, so 500 ml would weigh approximately 750 grams.
What is the word equation for the reaction between hydrogen and fluorine?
The word equation for the reaction between hydrogen and fluorine is "hydrogen + fluorine -> hydrogen fluoride."
How many product atoms are there in hydrogen?
There is one atom of hydrogen in a hydrogen molecule.
What is difference between hydrogen sulfide and hydrogen sulphide?
There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.
Is hydrogen a molecule?
Yes, hydrogen can exist as a molecule. In its diatomic form, hydrogen atoms can bond together to form a molecule called molecular hydrogen (H2).
How much does 50 percent hydrogen peroxide weigh per gallon?
Hydrogen peroxide has a density of about 1.2 kg/L. Therefore, 50% hydrogen peroxide by weight would weigh approximately 6.6 pounds per gallon.
Do oxygen and hydrogen and carbon dioxide weigh the same?
No, oxygen, hydrogen, and carbon dioxide do not weigh the same. They have different atomic masses, with oxygen being heavier than hydrogen and carbon dioxide being heavier than both oxygen and hydrogen.
Weight of cubic meter of hydrogen?
Depends on the pressure. Assuming standard pressure, hydrogen's density (as a gas) is 0.0899 kg/m^3. If you have one cubic meter of hydrogen, it will weigh .0899 kg.
Does a mole of water weigh the same as a mole of hydrogen?
No. A mole of hydrogen (in its normal form) weighs 2 grams. A mole of water weighs 18 grams.
An empty barrel weighs 9kilograms what can you put in the barrel to make it weigh 8 kilograms?
You can put a hole in the barrel to make it weigh 8 kilograms.
How much is 500 cc's of hydrogen peroxide?
500 cc's of hydrogen peroxide is equivalent to 500 milliliters. Hydrogen peroxide has a density of 1.5 g/ml, so 500 ml would weigh approximately 750 grams.
Which gas is filled in football in international matches?
its hydrogen gas Thats why it is so light in weigh..
When a pair of hydrogen isotopes is fused is the mass of the product nucleus more or less the sum of the masses of the two hydrogen nuclei?
Because of conservation of matter the nucleus would weigh the same as the sum of the two isotopes.
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
How much does 35 percent hydrogen peroxide weight per gallon?
Hydrogen peroxide has a density of about 1.2 grams per milliliter. To convert this to pounds per gallon, there are roughly 3.785 liters in a gallon (1 gallon = 3.785 liters) and 1 gram is about 0.00220462 pounds. Therefore, 35% hydrogen peroxide would weigh approximately 16.7 pounds per gallon.
How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
Is Hydrogen gas lighter than air or heavier than air?
Hydrogen gas is 16x lighter than air. The atomic weight of Hydrogen is 1 atomic mass unit, and the atomic weight of oxygen is 16 atomic mass units. 602,000,000,000,000,000,000,000 hydrogen molecules would weigh 1 gram. The same amount of oxygen would weigh 16 grams. Clarification: The air we breath is actually a mixture of oxygen, nitrogen, and carbon dioxide. But in this example, I treated it as pure oxygen to keep things simple.
