If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. What is the expected mass of AgBr in grams? Solution The two equilibria involved are: . Clergy & Staff Contacts. The molar ratio is 1/2, so if we start with 20.5 moles of NaBr, we'll get 10.25 moles of NaB. We may calculate reactant and product amounts using balanced chemical equations thanks to the fundamental concept of stoichiometry. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. The reason is that the molar mass of the substance affects the conversion. 2$qo-fk,XnJi2!8mV*Gxi@fnj6Th &Sa~L$U+s-N-\Yuva[Qw,L1PHfpPBT(uW^JxoRV~Gg{X>J^+Y5@-fBe2|HhtFAT0''zDi[d`t7@#U[]#'0h|9&-MZs"%RiGGGGZLHDa+GhG4?/~
