Molar masse h

Molar mass of H is 1.007940 ± 0.000070 g/mol Convert between H weight and mole På samme måte finner man den molare massen til sprit C 2 H 5 OH å være 46,07 g/mol. Da det blir produsert to mol sprit for hvert mol glukose, blir det produsert 2×5,55 mol = 11,1 mol med sprit. Det tilsvarer nå en masse (46,7 g/mol)× (11,1 mol) = 511 g The molar mass of molecules of these elements is the molar mass of the atoms multiplied by the number of atoms in each molecule: M (H 2 ) = 2 × 1.007 97(7) × 1.000 000 g/mol = 2.015 88 (14) g/mo

Molar masse er innen fysikk og kjemi det samme som massen av et mol atomer eller molekyler. Den molare massen for et stoff angis i gram per mol, altså g/mol. Når den molare massen for et stoff er Mr g/mol, kalles tallet Mr den relative molekyl- eller atommassen for stoffet. Molar masse = Masse av stoffet (kg) / Stoffmengde (Mol) Mole eller mol er enheten som brukes til å måle mengden av et stoff. En mol av et stoff er lik et veldig stort antall, 6,023 x 10 23 av atomer (eller molekyler) som stoffet er laget av. Dette nummeret kalles Avogadros nummer
