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.

Kodi ndi molekula kutalika anawerengedwa?
Kuwonjezera pa kutalika kwa atomu, tiyeneranso kuganizira kuti madzi (H₂O) ali ndi 2 × 1.008 + 15.999 = 18.015 g/mol, ndipo kutalika kwa atomu kumadalira kuchuluka kwa ma atomu omwe ali m’mafuta.
Kodi formula syntax ndi wothandiza?
Ca(OH)2 imawerengedwa ngati calcium imodzi, oxygen ziwiri ndi hydrogen ziwiri; CuSO4.5H2O imaphatikizapo madzi asanu ndi awiri.
Kodi pali kusiyana kotani pakati pa mole ndi mole?
Molecular kutalika (kapena molecular masa) ndi chigawo cha 10-12 m m'lifupi kwa mole; molar kutalika ndi kutalika kwa mole m'lifupi kwa gramu pa mole. Molecular kutalika ndi kutalika kwa mole m'lifupi kwa gramu pa mole.
Kodi ndingapeze bwanji hydrate monga copper sulfate pentahydrate?
Kugwiritsa ntchito dot pamaso pa madzi gulu: CuSO4.5H2O. Kuyambira 5 amadutsa H2O, kuwonjezera 5 madzi a crystallization, ndi calculator amabwerera 249.68 g / mol kwa hydrate.
Kodi ndi perekani kusonkhanitsa kwa peresenti yomwe ikusonyeza?
Pa madzi, oxygen ndi pafupifupi 88.8% ndi hydrogen 11.2%; mu glucose, carbon ndi 40.0%, hydrogen 6.7% ndi oxygen 53.3% — zothandiza kwa empirical-formula ndi ntchito kuwala.
N’chifukwa chiyani formula wanga sanathe kugawa?
Mtundu uliwonse wa element umafunika kulemba bwino (Co ndi cobalt, koma CO ndi carbon ndi oxygen), ndipo element yachidule yokha imavomerezedwa. Kangani kuti pali ma symbols opanda ma fonts, ma brackets osagwirizana kapena zolemba zoipa ngati mukuona vuto la kugawa.
Kodi ndingawerengere molar mass ya polyatomic ion kapena gulu?
Yes — khoma gulu mu zilembo ndi multiplier yake, monga Ca (OH) 2 kapena (NH4) 3PO4. parser amafalitsa zilembo ndi multiplies mkati atomu, choncho ammonium fosfatet sumas bwino pakati pa onse atatu amoniamu mabungwe.
