The molecular weight, or molar mass, of a compound is the mass of one mole of it in grams per mole, found by adding up the standard atomic weight of every atom in its chemical formula. This molecular weight calculator parses a formula you type — element symbols with optional subscripts, nested parentheses, and a leading multiplier for hydrates — and sums the atomic weights, drawing on IUPAC standard values (hydrogen 1.008, carbon 12.011, oxygen 15.999, and so on).
As a worked example, water H2O contains two hydrogen atoms and one oxygen: 2 × 1.008 + 15.999 = 18.015 g/mol. Glucose C6H12O6 sums to 6 × 12.011 + 12 × 1.008 + 6 × 15.999 = 180.156 g/mol. The calculator also returns a per-element breakdown showing each element’s atom count, atomic weight, mass subtotal and percentage of the total mass — so for water it reports oxygen as about 88.8% of the mass and hydrogen the rest.
The parser understands parentheses and hydrate dot-notation, so Ca(OH)2 is read as one calcium, two oxygen and two hydrogen (74.09 g/mol) and CuSO4.5H2O includes the five waters of crystallisation (249.68 g/mol). Molar mass is the essential bridge between the mass you weigh on a balance and the moles a reaction needs, so it underlies solution preparation, reaction stoichiometry, yield calculations and converting between grams and moles at every step of quantitative chemistry.

Gịnị bụ pasentị nke nrụnye ọ na-egosi?
N'ime mmiri, oxygen bụ ihe dịka 88.8% na hydrogen 11.2%; na glucose, carbon bụ 40.0%, hydrogen 6.7% na oxygen 53.3% - bara uru maka empirical-formula na ọrụ nchebe.

M ga-ejide molar mass nke polyatomic ion mọọbụ group?
Yes — wrap the group in parentheses with its multiplier, like Ca(OH)2 or (NH4)3PO4. The parser expands the parentheses and multiplies the enclosed atoms, so ammonium phosphate sums correctly across all three ammonium groups.
