Mass Of Hydrogen Atom In Kg

Molar mass of H = 1.00794 g/mol

Answer to If the mass of a hydrogen atom is 1.67 X 10-27 kg and the mass of an electron is 9.1 X 10-31 kg, how many electrons.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.

Hydrogen weighs 0.000082 gram per cubic centimeter or 0.082 kilogram per cubic meter, i.e. Density of hydrogen is equal to 0.082 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure. In Imperial or US customary measurement system, the density is equal to 0.0051 pound per cubic foot lb/ft³, or 0.0000474 ounce per cubic inch oz.

Calculate the molar mass of Hydrogen in grams per mole or search for a chemical formula or substance. A proton, which is the nucleus of a hydrogen atom, can be modeled as a sphere with a diameter of 2.4 fm and a mass of 1.67 10-27 kg. 1 GeV/c2 = 1.782 661 92 × 10−27 kg. The unified atomic mass unit (u), almost exactly 1 gram divided by the Avogadro number, is almost the mass of a hydrogen atom, which is mostly the mass of the proton. To convert to electron volts, use the formula: 1 u = 931.4941 MeV/c2 = 0.931 4941 GeV/c2.

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.

How can I calculate the densities of a hydrogen nucleus and a hydrogen atom?

1 Answer

You use the formula for density and the published radii to calculate the densities. The values are #6.70 × 10^14'kg/dm'^3# and #2.7'kg/dm'^3#.

Explanation:

The formulas to use are

#'Density' = 'mass'/'volume'# or #ρ = m/V# and

#V = (4/3)πr^3#

Hydrogen nuclei

A hydrogen nucleus is a proton, and the mass of a proton is #1.67 × 10^(-27)'kg'#.

The most recent value for the radius of a proton is #8.41 × 10^(-16)'m'#.

#V = (4/3)πr^3 = (4/3)π(8.41 × 10^-16'm')^3 = 2.49 × 10^(-45)'m'^3#

#ρ = m/V = (1.67 × 10^(-27)'kg')/(2.49 × 10^(-45)'m'^3)= 6.70 × 10^17'kg/m'^3 = 6.70 × 10^14'kg/dm'^3#

H atoms

State The Mass Of One Atom Of Hydrogen In Kg

The mass of a hydrogen atom is #1.67 × 10^(-27)'kg'#.

The radius of a hydrogen atom, calculated using self-consistent field functions, is #'53 pm'# or #53 × 10^(-12)'m'#.

Mass Of Hydrogen 1

#V = (4/3)πr^3 = (4/3)π(53 × 10^(-12)'m')^3 = 6.24 × 10^(-31)'m'^3#
