What the tool does, how to run it, and what to expect from the result.
Type a chemical formula and read the molar mass in grams per mole. Each element’s count is multiplied by its standard atomic weight and summed: water is 2 × 1.008 + 15.999 = 18.015 g/mol. Groups like Ca(OH)2 and K4[Fe(CN)6] and hydrates written with a dot are expanded automatically, and the table shows each element’s share of the mass. Element symbols are case-sensitive: Co is cobalt, CO is carbon monoxide.

Short answers for the questions people usually have before trying a utility like this.
Numerically, yes. Molar mass is in grams per mole; molecular weight (relative molecular mass) is the same number without units, or in daltons for a single molecule. Glucose, C6H12O6, is 180.156 g/mol.
IUPAC conventional values for common elements, such as 1.008 for hydrogen, 12.011 for carbon and 15.999 for oxygen, and standard values for the rest. Results can differ from a textbook in the last decimal if it rounds differently.
