Using stoichiometry, 16.2 L of H2 gas at STP equals about .7228 moles (1 L of gas at STP has a volume of 22.41 L), and there are 6.02 x 1023molecules of hydrogen in a mole, so we have (6.02 x 1023molecules/mol)(.7228 mol) = 4.35 x 1023 hydrogen molecules. There are two hydrogen atoms in each molecule, so the answer is (4.35 x 1023molecules H2)(2 H atoms/molecule) = 8.70 x 1023 H atoms in 16.2 L.

How many moles of of hydrogen gas occupy 112L at stp?
Ideal gas equation. PV = nRT ===============
A sample of 90 g water was decomposed using electrolysis How many liters of hydrogen where produced at STP?
60 grams.
How many grams of oxygen gas is contained in 11.2L 02 gas at stp?
To determine how many atoms are present in 56 liters of oxygen gas at STP you first need to know that there are two atoms in a single molecule. Then, you would work the scientific formula to determine the number of molecules in the oxygen gas.
What would be the volume of 6.00 g of helium gas at STP?
If these atoms are loose unities, not bonded in a molecule, it would be about 22 dm3 at 0oC and standard pressure (STP). If the atoms would have formed gas molecules, e.g. CO2 or SF6, the answer would be different, because 6.02 x 1023 molecules always take in a volume of about 22 dm3 at STP. But with CO2 you would have then 18 x 1023 atoms because there are 3 atoms in one molecule.
What volume is occupied of 0.48 moles of hydrogen?
0.48 liters at STP (standard temperature and pressure)
How many atoms in 560cm3 of ammonia at stp?
The number of atoms is 5,162.10e23.
Does water come from atoms?
Like all material things that exist, water is made from atoms. Water is made specifically from hydrogen and oxygen atoms, elements that are in the form of gas when at stp and not combined.
At STP which element is a solid hydrogen or iodine?
Iodine is a solid at STP.
What do you know about all of atoms in the elements oxygen?
2 atoms of oxygen joined togetherBy mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At STP, two atoms of the element bind to form dioxygen.

Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
