The Molar Mass Calculator is a tool used to calculate the molar mass of a substance based on its chemical formula. Molar mass is the mass of one mole of a substance and is expressed in grams per mole.

To use the calculator, simply input the chemical formula of the substance and click the "Calculate" button. The calculator utilizes the periodic table of elements to determine the atomic weights of the elements present in the formula. It then calculates the molar mass by adding up the atomic weights of all the elements in the substance.

In addition to the molar mass, the calculator also provides a result table with detailed information on the individual elements in the formula. 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.

It is important to ensure that the chemical formula is entered correctly using standard notation. For example, C2H5OH for ethanol, H2O for water, or Na2SO4 for sodium sulfate. By following the standard notation, you can avoid ambiguity in parsing and obtain accurate results.
