![]() By following the standard notation, you can avoid ambiguity in parsing and obtain accurate results. For example, C2H5OH for ethanol, H2O for water, or Na2SO4 for sodium sulfate. It is important to ensure that the chemical formula is entered correctly using standard notation. For instance, the relative atomic mass of zirconium (Zr) is 91.22. This is usually located under the symbol and name of the element. To find an element’s molar mass, start by checking the periodic table for the relative atomic mass of the element. The result table includes the element symbol, atomic mass, multiplier (indicating the number of atoms of each element in the formula), and the calculated result. Molar mass is the mass in grams of 1 mole of any given substance. In addition to the molar mass, the calculator also provides a result table with detailed information on the individual elements in the formula. It then calculates the molar mass by adding up the atomic weights of all the elements in the substance. The calculator utilizes the periodic table of elements to determine the atomic weights of the elements present in the formula. To use the calculator, simply input the chemical formula of the substance and click the "Calculate" button. For elements without stable isotops, the mass number for the isotop with the longest half-life is given in parenthesis. ![]() Molar mass is the mass of one mole of a substance and is expressed in grams per mole. Average atomic mass is the same number as molar mass, however, the unit for molar mass is g/mol. American Chemical Society 57-71 Lithium 6.94 Beryllium 9.012 Sodium 22.99 Magnesium 24.31 Francium (223) Radium (226) Rutherfordium (265) Dubnium. The Molar Mass Calculator is a tool used to calculate the molar mass of a substance based on its chemical formula.
