Any chemical element. 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.Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, Dmgparenthesis () or brackets .Common compound names.Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×1023particles (Avogadro's number)Identify the compound: write down the chemical formula of the compound. For example, water is H2O, meaning it contains two hydrogen atoms and one oxygen atom.Find atomic masses:look up the atomic masses of each element present in the compound. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu).Calculate molar mass of each element:multiply the atomic mass of each element by the number of atoms of that element in the compound.Add them together:add the results from step 3 to get the total molar mass of the compound.Let's calculate the molar mass of carbon dioxide (CO2): 1. Carbon (C) has an atomic mass of about 12.01 amu. 2. Oxygen (O) has an atomic mass of about 16.00 amu. 3. CO2has one carbon atom and two oxygen atoms. 4. The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol.
Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate , an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH)
Dec 26, 2016 · From the chemical formula, there are 2 iron atoms, so the atomic mass has to be multiplied by 2, which gives you a value of 111.7 g/mol. Next, you have 3 oxygen atoms, so you would multiply the atomic mass of O by 3 to obtain an atomic weight of 48.00 g/mol.
If we were to ask how many grams of elemental iron will be formed by the reduction of 1.0 grams of iron (III) oxide, we would simply use the molar stoichiometry to determine the number of moles of iron that would be produced, and then convert moles into grams using the known molar mass.
