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.

Who created hydrogen?
how made hydrogen how made hydrogen how made hydrogen how made hydrogen
What does h stand for in h20?
Hydrogen. The lightest element.
What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
Is hydrogen poisonous?
Hydrogen is not poisonous.
Who has the stronger dipole-dipole hydrogen chloride or hydrogen flouride?
Hydrogen fluoride as it is a hydrogen bond.
Do oxygen and hydrogen and carbon dioxide weigh the same?
No, hydrogen, oxygen and carbon dioxide have very different weights.
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.
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?
Oxygen atoms weigh more than Hydrogen atoms.
An empty barrel weighs 9kilograms what can you put in the barrel to make it weigh 8 kilograms?
Helium/hydrogen
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.
How much does a mole of nh3 weigh?
nitrogen weighs 14, hydrogen weighs 1, so NH3 weighs 14+(3x1)=17grams
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.
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)
What atom has an atomic number of 1?
Hydrogen Hydrogen Hydrogen Hydrogen
What is hydrogen and hydrogen gas?
hydrogen and hydrogen gas are same hydrogen is gas
