Now lets find out how many moles of each of the products KMnO4 yields..01225 moles * (2mol K2SO4 / 1 mol KMnO4) = .0245 mol K2SO4. b) M/2 Try again. Equivalent weight in redox system is defined as : E= (Molar mass)/(n-factor) Here n-factor is the net change in oxidation number per formula unit of oxidizing or reducing agent. The equivalent weight of MnSO4 is half its molecular weight when it is converted into (A) Mn2O3 (B) MnO-4 (C) MnO2 (D) MnO2-4. If M is the molecular weight of KMnO4, what is the equivalent mass of KMnO4 when it is converted into K2MnO4? Equivalent weight = 184 g/mol / no. UN1490. Use the sample mass and the equivalent weight to calculate the number of equivalents of oxalate in each sample. Thus, the equivalent mass = molecular mass/1 = molecular mass = M. Hence, the equivalent mass of KMnO4 is M when it converts over to K2MnO4. Equivalent Weight = Molecular Weight / No. Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. Nov 30,2020 - The equivalent weight of MnSO4 is half of its molecular weight when it is converted to : (1988 - 1 Mark)a)Mn2O3b)MnO2c)MnO4-d)MnO42-Correct answer is option 'B'. 392 = 19.6 g/L which the iron is converted into K2MnO4 is - 8675024 M is the gram weight...
