![]() No responsibility is taken for the correctness of this information.Ĭhemical Calculators © Jumk. This calculator requires the user to input the amount of a template present (in ngs) and. Chemical formula: Enter any chemical formula optionally with. Relative Molar Mass Calculator for Chemists. In air, which is about 78.1 percent nitrogen (N 2) and 20.9 percent oxygen (O 2), the ratio is 3.27. The molecular mass calculator will recognize the entered formulas, which are included in the list of organic compounds. This website may save cookies from advertisers. Both molecular masses and the ratios to each other will be calculated.Įxamples: The water molecule H 2O has a mass ratio of oxygen to hydrogen of 7.94. The amount of each molecule can be specified if this is omitted, 1 is assumed as the amount. Please enter the empirical formula of two molecules, the entry format is similar to the molecular mass calculator. ![]() Here the ratio of the masses of molecules or atoms can be calculated. This molar mass calculator can only handle two bracket levels at a time.Chemical Calculators | Atomic Masses | Molecular Mass | Mass Ratio | Atoms per Mass | Molar Mass | Isotopes | Neutron-Proton Ratio | Mixing Ratio | pH Dilution | Ideal Gas Law | Concentration | Saline Solution | Half-life | Heat Capacity | Vaporization | Mix Temperatures | SI Prefixes Mass Ratio The periodic table lists the atomic mass of carbon as 12.011 amu the average molar mass of carbonthe mass of 6.022 × 10 23 carbon atomsis therefore 12. Tricalcium phosphate would be entered as Ca3(PO4)2. The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole. 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. This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ). 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. Now, if we know that the molar mass of the compound under study is 180.16 g/mol, we can find the molecular formula of this compound. The relative atomic mass is the same as the molar mass (except molar mass is in g/mol). Do this by looking up sodium (Na) on the periodic table. For example, find the mass of one mole of sodium. Electron Multiplier for Agilent 5973 (many more available) Rotary vane or dry pumps, including affordable SIS pump. Example 1: Find the Molar Mass of an Element. Many other calculations require conversion into moles. NIST 14 MS Library - Identify Mass Spectra. The procedure to use the molar mass calculator is as follows: Step 1: Enter the chemical compound in the respective input field. The Density Calculator uses the formula pm/V, or density (p) is equal to mass. 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 Free online physics calculators, velocity equations and density, mass and. 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.
