Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Sidee ayaa miisaanka molecular la xisaabiyaa?
Ku baddal miisaanka atomiga ee qayb kasta oo ka mid ah inta atom ee foomka ku jira, ka dibna ku dar iyaga. Biyo (H₂O) waa 2 × 1.008 + 15.999 = 18.015 g / mol.
Waa maxay qaabka qoraalka formula la taageerayo?
Calaamadaha qaybta oo leh tirakoobyo ikhtiyaari ah, isku-dhafka isku-dhafka ah iyo kobcinta ugu weyn ee hydrates. Ca (OH) 2 waa in la akhriyo sida hal calcium, laba oksijiin iyo laba hydrogen; CuSO4.5H2O waxaa ku jira shan biyo.
Waa maxay farqiga u dhexeeya miisaanka molecular iyo miisaanka molar?
Tirada waxay leeyihiin qiimaha isku mid ah. miisaanka Molecular (ama miisaanka Molecular) waa sawir la xiriira daltons for mole oo keliya; miisaanka molar waa miisaanka mol in gram per mol. Labaduba waa isku mid miisaanka atomiga ee la soo ururiyey.
Sidee baan u galaya hydrate sida copper sulfate pentahydrate?
Ku isticmaal dhibic ka hor inta aan kooxaha biyaha: CuSO4.5H2O. 5 ugu horeysay ayaa la kordhiyaa H2O, oo ay ku jiraan shan biyo oo crystallization, iyo xisaabinta ku soo laabtay 249.68 g / mol ee hydrate.
Waa maxay boqolkiiba ka kooban yahay uu muujinayo?
Biyo, oksijiin waa ku saabsan 88.8% iyo hydrogen 11.2%; in glukooska, carbon waa 40.0%, hydrogen 6.7% iyo oksijiin 53.3% - faa'iido u ah empirical-formula iyo daahirnimo shaqada.
Maxaa keenay formulayga ku fashilmeen in ay falanqeeyaan?
Calaamadda qayb kasta waa in si sax ah loo daabaco (Co waa cobalt, laakiin CO waa carbon iyo oksijiin), iyo kaliya qaybaha dhabta ah ayaa la aqbali doonaa. Ka hubi calaamadaha yaryar, isku mid ah ama tifaftirka haddii aad aragto khalad falanqeynta.
Ma awoodaa inaan xisaabiyo miisaanka molar ee polyatomic ion ama koox?
Haa - ku shub kooxaha ku jira isku darka isku darka, sida Ca (OH) 2 ama (NH4) 3PO4. Parser-ka wuxuu ballaariyaa isku darka oo wuxuu ku kordhiyaa atoms-ka ku xiran, sidaas darteed ammonium phosphate wuxuu si sax ah ugu soo ururiyaa saddexda kooxood ee ammonium.
