The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol. Sodium chloride, also known as salt, common salt, table salt or halite, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. Moles allow you to directly read weight from the periodic table (e.g., 1 mole of N is 28 g or 1 mole of NaCl is 58.5 g).CO 2 has one carbon atom and two oxygen atoms.Oxygen (O) has an atomic mass of about 16.00 amu.The chloride ions are arranged in a cubic array with respect to one another, while the. The chloride ions are much larger than the sodium ions. The arrangement forms a regular octahedron. In the solid lattice, each ion is surrounded by six ions having an opposite electrical charge. Carbon (C) has an atomic mass of about 12.01 amu. The molecular formula of table saltsodium chlorideis NaCl.Let's calculate the molar mass of carbon dioxide (CO 2): Add them together: add the results from step 3 to get the total molar mass of the compound.Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound.The atomic mass is usually found on the periodic table and is given in atomic mass units (amu). To two decimal places, the formula mass of NaCl is 58.44 amu. Find atomic masses: look up the atomic masses of each element present in the compound. This formula mass is the sum of the atomic masses of one sodium atom and one chlorine atom, which we find from the periodic table here, we use the masses to two decimal places: Na: 22.99 amu.For example, water is H 2O, meaning it contains two hydrogen atoms and one oxygen atom. Identify the compound: write down the chemical formula of the compound.One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules.Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations: Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass) Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, DmgĮxamples of molar mass computations: NaCl, Ca(OH)2, K4, CuSO4*5H2O, nitric acid, potassium permanganate, ethanol, fructose, caffeine, water.Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
