››Convert moles Oxygen to gram

To calculate the atomic mass of oxygen using the data in the above table, we must first multiply the mass of each isotope by its corresponding natural abundance (percentage abundance). But, since the abundance is in%, you must also divide each abundance value by 100. Oxygen-15 atom is the radioactive isotope of oxygen with relative atomic mass 15.003065. The longest-lived oxygen radionuclide with half-life of 122.2 s. The atomic mass of oxygen is 15.9994 atomic mass units. Oxygen has an atomic number of 8 and is classified as a non-metal. Its symbol is O. Oxygen was discovered in 1774 by Joseph Priestly, according to Chemical Elements. Physicists, however, dealing with atoms and not reagents, required a unit that distinguished between isotopes. At least as early as 1927 6 physicists were using an atomic mass unit defined as equal to one-sixteenth of the mass of the oxygen-16 atom (the isotope of. How many moles Oxygen in 1 grams?

››Details on molecular weight calculations

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.

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.

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.

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.

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.

Dry air is a mixture of gases where the average molecular weight (or molar mass) can be calculated by adding the weight of each component

The molecular weight (or molar mass) of a substance is the mass of one mole of the substance, and can be calculated by summarizing the molar masses of all the atoms in the molecule.

Components in Dry Air

Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol% oxygen and 78 vol%nitrogen. Oxygen has a molar mass of 15.9994 g/mol and nitrogen has a molar mass of 14.0067 g/mol. Since both of these elements are diatomic in air - O₂ and N₂, the molar mass of oxygen gas is aprox. 32 g/mol and the molar mass of nitrogen gas is aprox. 28 g/mol.

Atomic Mass Of Oxygen Atom

The average molar mass is equal to the sum of the mole fractions of each gas multiplied by the molar mass of that particular gas:

M_mixture = (x₁*M₁ + ......+ x_n*M_n) (1)

where

x_i = mole fractions of each gas
M_i = the molar mass of each gas

The molar mass of dry air with oxygen, nitrogen and the other components as indicated below is 28.9647g/mol. Composition and content of each gas in air is given in the figures and the table below.

Air Density

The density of dry air can be calculated with the Ideal Gas Law

ρ = P / (R T) (1)

where

P = pressure (Pa)

R_air = 287.05 = individual gas constant [J/kg K]

T = absolute temperature [K]

Example: The density of dry air at atmospheric pressure 101.325 kPa (101325 Pa) and 0 ^oC (= 273.15 K) can be calculated as

ρ = 101325 [Pa] / (287.05 [J/kg K]*273.15 [K])

= 1.292 [kg/m³]

Water Vapor

Water vapor is almost always present in air. The content may vary and the maximum amount possible of water vapor in dry air depends on the temperature of the air.

Water vapor - H₂O - is composed of one oxygen atom and two hydrogen atoms. Hydrogen is the lightest element with a molar mass of 1 g/mol, while oxygen has 16 g/mol. Thus, the water vapor atom has an molar mass of 18 g/mol, and water vapor is lighter than O₂ with 32 g/mol and N₂ with 28 g/mol.

• Note! Water vapor in air will dilute the other gases and reduce the total density of the mixture. Dry air is more dense than humid air!

The vapor in air may saturate to droplets when temperature is decreased or pressure is increased.

Humid air containing water molecules as liquid - droplets - may be more dense than dry air or humid air containing water only as vapor.
