Step 2: Now click the button Calculate Molar Mass to get the result. Weights of atoms and isotopes are from NIST article. The procedure to use the molar mass calculator is as follows: Step 1: Enter the chemical compound in the respective input field. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.STP only identifed the temperature (273 K) and pressure (101.3 kPa). (1 u is equal to 1/12 the mass of one atom of carbon-12) Answer: The volume of any gas, under any temperature or pressure conditions will depend on the amount of gas you have. Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). Governing Equation: Molar mass m N M kg kmol kgkmol/ Properties: Molar mass of.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:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of N2 is 28. 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) Molar Mass, Molecular Weight and Elemental Composition Calculator.
