Argon Mass Number
About Argon; Argon weighs 0.0017838 gram per cubic centimeter or 1.7838 kilogram per cubic meter, i.e. Density of argon is equal to 1.7838 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 0.11136 pound per cubic foot lb/ft³, or 0.0010311 ounce per cubic inch oz/inch³.
Molar mass of Ar = 39.948 g/mol
- I assume this is for a chemistry class or something, and are probably expected to determine this using molar mass and avogadro's number (6.022e23 atoms per mole) 1 mole of gold is 196.97 grams since 196.97 is the molar mass. A mole of anything, has 6.022e23 atoms (for elements) or molecules (for compounds) per 1 mole of whatever substance it is.
- Do a quick conversion: 1 moles Argon = 39.948 gram using the molecular weight calculator and the molar mass of Ar. Check the chart for more details.

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.
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.
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.
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.

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.
