Stoichiometry One of the specific gravity scales is "Brix" (used speicifically for sugar solution). It is defined as Brix = (400/G) - 400 None of these Brix = 200 (G-1) Brix = 145 - (145/G) Brix = (400/G) - 400 None of these Brix = 200 (G-1) Brix = 145 - (145/G) ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2.

Stoichiometry According to Raoult's law, "The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component." Raoult's law is not applicable under the following assumption/condition. In the formation of solution, chemical combination/molecular association between unlike molecules takes place The component molecules are non polar and are of almost equal size No component is concentrated at the surface of the solution The attractive forces between like and unlike molecules are almost equal In the formation of solution, chemical combination/molecular association between unlike molecules takes place The component molecules are non polar and are of almost equal size No component is concentrated at the surface of the solution The attractive forces between like and unlike molecules are almost equal ANSWER DOWNLOAD EXAMIANS APP
