Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Ubunzima be-molecule bucalwa kanjani?
Multiply each element’s atomic weight by how many atoms of it the formula contains, then add them up. Water (H₂O) is 2 × 1.008 + 15.999 = 18.015 g/mol.
Yini ifomula yezinhlamvu ezixhaswe?
Izimpawu zengxenye ezinombalo okhethiwe, iziqongo ezifakwe ngaphakathi kanye nokuphindaphinda okuphambili kwe-hydrates. Ca(OH)2 ifundwa njenge-calsium eyodwa, i-oxygen ezimbili ne-hydrogen ezimbili; CuSO4.5H2O ifaka amanzi amane.
Yini ushintsho phakathi kwesisindo se-molecule nesisindo se-molar?
Isisindo se-molecule (noma isisindo se-molecule) yisithombe esiphathelene nge-daltons se-molecule eyodwa; isisindo se-molar yisisindo se-molecule nge-grams ngayinye ye-mole. Zonke zilingana nesisindo se-atomic esiphelele.
Ngizofaka kanjani i-hydrate njenge-copper sulfate pentahydrate?
Sebenzisa inkinobho phambi kweqembu lolwandle: CuSO4.5H2O. Inombolo engu-5 ephambili iphinda i-H2O, ingeza amanzi amahlanu okukristalu, futhi i-calculator ibuyisela 249.68 g/mol yale hydrate.
Yini iphesenti lokuhlanganisela elibonisa?
Kumanzi, i-oxygen ilingana ne-88.8% ne-hydrogen 11.2%; ku-glucose, i-carbon ilingana ne-40.0%, i-hydrogen ilingana ne-6.7% ne-oxygen ilingana ne-53.3% — esetshenziswa ku-empirical-formula nemisebenzi yobucwebe.
Kungani ifomu lami lihlulekile ukucutshungulwa?
Yonke into i symbol kumele ibhalwe ngobukhulu ngokulungile (Co i-cobalt, kodwa CO i-carbon plus oxygen), futhi izinto ezingokoqobo kuphela ezivunyelwe. Khangela izibonakaliso ezincane, iziqongo ezingalingani noma iziphutha zokuchwetheza uma ubona iphutha lokuhlukaniswa.
Ingabe ngingakwazi ukubala isisindo se-molecular se-polyatomic ion noma iqembu?
Yebo — cindezela iqembu ezindaweni ezihamba phambili nge-multiplier yayo, njenge Ca(OH)2 noma (NH4)3PO4. Isihlungi sithuthukisa izindonga futhi siphindaphinda ama-atomi afakwe ngaphakathi, ngakho-ke i-ammonium phosphate ihlanganisa ngokulungile phakathi kwazo zonke izinhlangano ezintathu ze-ammonium.
