Carbon dioxide is also a naturally occurring greenhouse gas in the Earth’s atmosphere and is formed via the activity of volcanoes, hot springs, animal respiration, fire, and geological movement. Carbon dioxide is a natural byproduct of the cellular respiration cycle in animals and one of the main reactants processed during plant photosynthesis. At room temperatures, carbon dioxide is a colorless odorless gas that is 60% denser than normal air.

You can also use our molar mass calculator.Carbon dioxide is a covalent compound composed out of two oxygen atoms double bonded to a carbon atom.

Basically, you should know how to find the molar masses of any chemical compound now.

Of nitrogen) + (six atoms x 16 grams/mole of oxygen) = 189 grams/mole ofįor all other compounds, the general idea is the same. Will be equal to (1 atom x 65 grams/mole of zinc) + (two atoms x 14 grams/mole The brackets multiplied by the subscript two). Multiplied by the subscript two) and six atoms of oxygen (three atoms in Have one atom of zinc, two atoms of nitrogen (one atom inside the brackets (1 atom x 56 grams/mole Fe) + (2 atoms x 35.5 grams/mole of chlorine) = 127 grams/mole of iron (II) chloride For example, in iron (II) chloride, or FeCl 2, you have one atom of iron and two atoms of chlorine.

If you have a subscript in a chemical formula, then you multiply the number of atoms of anything next to that subscript by the number of the subscript.įor most compounds, this is easy. (1 atom x 23 grams/mole Na) + (1 atom x 35.5 grams/mole Cl) = 58.5 grams/mole NaClĢ. If we write this as a calculation, it looks like this:

If we have a chemical compound like NaCl, the molar mass will be equal to the molar mass of one atom of sodium plus the molar mass of one atom of chlorine. Molar masses of chemical compounds are equal to the sums of the molar masses of all the atoms in one molecule of that compound. To do this, we need to remember a few rules.ġ. How can I find the molar mass of a chemical compound?įor any chemical compound that's not an element, we need to find the molar mass from the chemical formula. Still, aside from the exceptions above, all elements have the same molar mass as the atomic masses on the periodic table. phosphorus is normally found in clumps of four atoms, P 4, and sulfur is found in clumps of eight atoms, or S 8. That each molecule of the element has two atoms of that element stuck together.Īs a result, the formula of hydrogen is H 2, nitrogen is N 2, etc. In the case of hydrogen, nitrogen, oxygen,įluorine, chlorine, bromine, and iodine, the element is diatomic, meaning In some cases, the element is usually found in a differentįorm than just one unbonded atom. So, in our example, carbon has a molar mass of 12.01 grams per mole. For example, if you want to find the molar mass of carbon, you would find the atomic mass of carbon on the periodic table, and this is equal to the molar mass in grams per mole. The molar mass of elements is found by looking at the atomic mass of the element on the periodic table. How can I find the molar mass of an element? It is also sometimes called: Molecular Mass, Molecular Weight, Formula Mass, or Formula Weight. One atomic mass unit (u) is equal to 1/12 the mass of one atom of carbon-12. Molar mass is the mass (in atomic mass units) of one mole of a of a substance.
