In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly.

Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements.
This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ).

The formula tells us that water has two elements, hydrogen, and oxygen. Question 2: What is the importance of the formula H 2O of water? O 2 indicates that one molecule of oxygen element contains 2 atoms of oxygen and 2O indicates two separate atoms of oxygen. Question 1: What is the difference between O 2 and 2O? Formulae denote a definite mass of a substance.One molecule of a compound is represented by a formula.The number of atoms of each element contained in a molecule is given by formulae.The names of all the elements in the molecule are given in formulae.The compound’s name is represented by a formula.That is, 2H 2O is made up of four hydrogen atoms and two oxygen atoms. The 2 multiplies the entire H 2O formula rather than just the first element. 2H 2O, for example, indicates two water molecules. The symbol H in the formula H 2O stands for two hydrogen atoms, not a molecule of hydrogen, while O stands for one oxygen atom.
Water is a compound with two hydrogen atoms and one oxygen atom in each molecule. The chemical formulas and elements found in several common molecular compounds are listed below. In balanced chemical equations, a chemical formula is used to represent an element or compound. Most elements have only their chemical symbol as their formula.

Ions, free radicals, and other chemical species can all be represented using chemical formulas. While representing a compound in a chemical equation, its chemical formula is important. They also show the proportions in which the various constituents combine to generate the desired combination. A chemical formula gives information about the elements that make up a compound’s molecules, as well as the ratio in which these elements’ atoms combine to form those molecules.Ĭhemical formulae provide insight and distinction into a compound’s chemical composition. A compound’s chemical formula is a symbolic representation of the compound’s chemical composition. In other words, the formula of a compound tells us “the kind of atoms” present in one molecule of the compound, as well as the number of atoms of various elements present.Ī compound’s chemical formula is a description of its composition in which the chemical symbols indicate which elements are present and the subscripts indicate how many atoms of each element are present in one molecule. The chemical formula of a compound represents the elements present in the substance’s molecule in terms of their symbols.
