This molar mass calculator can only handle two bracket levels at a time. The above information can also be displayed in the following stoichiometry table: Atomic Mass. In the mass spectrum of glucose the nominal mass for M (6 x 12) + (12 x 1) + (6 x 16) 180, whereas the exact mass is (6 x 12.0000) + (12 x 1.007825) +. It does not report other isotopes and does not use the average masses of the elements. Calculations are based on the exact mass of the most abundant ion of the element. Tricalcium phosphate would be entered as Ca3(PO4)2. Here with the help of another molecular formula calculator, you can get to know the steps involved in calculating the molecular mass of any compound. The Exact Mass Calculator will provide the user with the exact mass of a chemical formula that is typed into the form below. For example, calcium carbonate would be entered as CaCO3, not caco3. The chemical formula should be entered using standard format. This calculator is a convenient tool for calculating the molar mass of chemical compounds in lieu of using a periodic table. These include consumption of pH adjustment chemicals for RO feedwater, solubilities of scale forming compounds in reverse osmosis systems, and cation rejection calculations using charge balance (meq/l) in nanofiltration systems. Many other calculations require conversion into moles. To simply convert from any unit into grams, for example, from 5 kilograms, just multiply by the conversion value in the right column in the table below. Knowing the desired concentration of ClO2, the system integrator can calculate the consumption of each of the reactants using the stoichiometric relationship:ĢNaClO2 + NaOCl + 2HCl ↔ 2ClO2 + H2O + 3NaCl This tool allows calculating the theoretical isotopic distribution and monoisotopic mass from a Molecular Formula. For example, certain types of chlorine dioxide (ClO2) generators would use sodium hypochlorite (NaOCl), sodium chlorite (NaClO2) and hydrochloric acid (HCl).
When calculating consumption of certain RO chemicals for reverse osmosis pretreatment or post-treatment, it is often necessary to convert into moles. The online calculator is currently unavailable.
