If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.

Mouseover on the chart to see the element name and Molar Volume of the element. Molar Volume Graph - Molar Volume of all the elements in graph. We have shown the Molar Volume of the elements for which reliable data is available. 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. Refer to graph, table and property element trend below for Molar Volume of all the elements in the periodic table. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. These relative weights computed from the chemical equation are sometimes called equation weights.įinding molar mass starts with units of grams per mole (g/mol).

This site explains how to find molar mass.įormula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. The reason is that the molar mass of the substance affects the conversion. To complete this calculation, you have to know what substance you are trying to convert. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.Ī common request on this site is to convert grams to moles. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Element Molar mass (g/mol) 9.012 40.08 Beryllium (Be) Calcium (Ca) Copper (Cu) Cadmium (Cd) lodine (I) 63.55 112.41 126.90 Match the numbers to the appropriate blanks in the sentences below. The mass in grams of 1 mol of a substance is called its molar mass. Given the atomic mass of select elements, calculate the molar mass of each salt. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. The average atomic mass of each element (expressed in amu) is also known as its. a pollution of 1 gram of benzene in a certain amount of water converts to N A/78.11≈ 7.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. Using the above calculator you could find that e.g. Or 1 mole of a substance will contain Avogadro's number of that substance. The term ' mole' is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as 'amu'.Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). 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. For question or remarks please contact us. It is the bridging quantity that connects the pair of physical quantities amount of substance and mass: M. MOLAR MASS (M) is defined as the mass (m) per unit amount of substance (n), i.e., per mole, e.g., M (U) 238 g/mol. !!! Lenntech BV cannot be held responsible for errors in the calculation, This term applies to ALL entities including elements in the atomic state. The formula weight is simply the weight in atomic. Make sure you enter the molecule of crystallization at last (e.g. The atomic mass in grams per mole is also equivalent to the characteristic molar mass of that element. The calculator handles at most two different bracket levels. The molecular mass calculator will recognize the entered formula's, which are included in the list of organic compounds.
