What is the mass of one atom in KG?
The mole is defined as a number of particles, 6.022 ´ 1023 particles to be accurate. To calculate the mass of a single atom of carbon, we just need to divide the molar mass of 12.0 g (0,012 kg) by the number of particles per mole (Avogadro's number). Doing so yields 1.99 ´ 10–26 kg as the mass of a carbon atom.
How many moles are in 1 kg of hydrogen?
1000The atomic mass of hydrogen is 1 g/mole. To make up 1 kilogram or 1000 g of hydrogen element, 1000 moles of hydrogen is required. Each mole has a Avogadro's number of atoms or atoms. Thus, 1 kg hydrogen element or 1000 moles of hydrogen have atoms (or 1000 times the Avogadro's number).
Is H2 molar mass 1 or 2?
A hydrogen, nitrogen, or oxygen molecule, consists of two identical atoms of each of those respective elements. Therefore, a hydrogen molecule's mass is 2 amu, oxygen is 32 amu and nitrogen is 28 amu.
How do you find the mass of a molecule?
To find the molecular mass, add the atomic masses of all of the atoms in the molecule. Find the atomic mass for each element by using the mass given in the Periodic Table.
How do you find the mass of one molecule?
Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.

What is the moles of H2?
H2 – There are 2 moles of hydrogen atoms (1 mole of elemental hydrogen). Total: 2 moles of atoms.
What is the mass of one molecule?
Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
How do you find the molecular weight of h2o?
Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen's is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.
What is the mass in grams of 1 molecule of H2O?
we have calculated the mass of one molecule of water as 2.989×10−23g.
What is the mass of a molecule?
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the 12C atom, which is taken to have a mass of 12.
How much hydrogen is in h2o?
two hydrogen A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.

How many molecules are present in 1kg of hydrogen?
1000The atomic mass of hydrogen is 1 g/mole. To make up 1 kilogram or 1000 g of hydrogen element, 1000 moles of hydrogen is required. Each mole has a Avogadro's number of atoms or atoms. Thus, 1 kg hydrogen element or 1000 moles of hydrogen have atoms (or 1000 times the Avogadro's number).
How many moles are in 2g of h2?
Thus, 1 mole is present in 2g of H₂ gas.
What is a H2 molecule?
Dihydrogen is an elemental molecule consisting of two hydrogens joined by a single bond. It has a role as an antioxidant, an electron donor, a fuel, a human metabolite and a member of food packaging gas. It is an elemental hydrogen, a gas molecular entity and an elemental molecule.

What is mass of water in kg?
Water has a density of 1 kg /L, that is, 1 liter of water has a mass of exactly 1 kg.
What is the mass in grams of 1 molecule of h2o?
we have calculated the mass of one molecule of water as 2.989×10−23g.
What is the mass of h2o?
18.01528 g/molWater / Molar mass
What is the mass of 1 molecule of o2?
Therefore; Mass of one molecule of oxygen = (32.0/ 6.022 × 1023) = 5.314 × 10-23 gram. Hence; Mass of one molecule of oxygen is 5.314 × 10-23 gram.
How do you find the mass of hydrogen?
As the mass of 1 proton is, 1.67×10−24g or 1.007 u, therefore this is the mass contained in a hydrogen atom. However, this mass resembles the atomic mass unit which is 1.66×10−24g. As this factor is simplified as 1.007 amu, therefore, hydrogen has a mass of 1.007 amu.
