For example, trimethyl borate can written as B(OCH3)3, BO3(CH3)3, (CH3)3BO3, or C3H9BO3.Ĭlick the image thumbnail to see the full-size periodic table of elements in a new tab or window. Element Name, Amount in Molecule, Mass Contribution. You can also use parentheses to denote chemical groups. Please Select Each Element and its Corresponding Amount in the Molecule. To enter a chemical formula into the molar mass calculator, use the IUPAC abbreviations for the elements. You can also use the convenient molar mass calculator on the left. You can easily calculate the molar mass of various compounds with the aid of a periodic table of elements, such as the one linked below. Since the atomic weight of hydrogen is 1.00794 and the atomic weight of oxygen is 15.9994, this means that the molar mass of water is 1.00794 + 1.00794 + 15.9994 = 18.01528. The molecular mass of SO 3 with 4 atoms in its molecule, is 1S 1 x 32.07 amu 32.07amu 3O 3 x 16.00 amu 48.00amu The molecular mass of SO 3 80. Solution: The molecular mass (or formula mass) of a compound is the sum of the atomic masses of all the atoms in the molecule. For example, one water molecule is made of two hydrogen atoms and one oxygen atom. So the calculation of the molecular mass of SO 3 is required first. The molar mass is simply the sum of the atomic weights of each element. Use Protein Molecular Weight when you wish to predict the location of a protein of interest on a gel in relation to a set of. You can append copies of commonly used epitopes and fusion proteins using the supplied list. To calculate the molar mass of a compound, you need to know its chemical formula and the atomic masses of each element that comprises the compound. Protein Molecular Weight accepts a protein sequence and calculates the molecular weight. For example, the molar mass of water (H 2O) is 18.01528 g/mol, which means that the weight of 6.0221415 x 10 23 water molecules is 18.01528 grams. 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. One mole of any quantity is equivalent to 6.0221415 x 10 23 units. The molar mass of elements is found by looking at the atomic mass of the element on the periodic table.

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).

Definitions of molecular mass, molecular weight, molar mass and molar weight. The molar mass of a compound (sometimes imprecisely referred to as molecular weight) is the weight of one mole of that substance expressed in grams per mole. Examples of molecular weight computations: C14O162, S34O162.
