How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
How many moles of electron needed in Faraday for reduction of 5 moles ofMnO−4(in acidic medium) View Solution 10 g of a mixture ofCu2Sand Cus was titrated with 200 " mL of " 0.75 MMnOɵ4in acidic medium producingSO2,Cu2+, andMn2+. TheSO2was boiled off and the excess ofMnO...
In order to determine the number of moles of a given compound, the first thing you need to do is find the molecular mass (or molecular weight) of the compound in question. Once you've done that, you need to determine how much the compound weighs physical
temperature,nis the number of moles of electrons transferred in the balanced equation,F=96500Cmol-1(the Faraday's constant),andQis the reaction quotient. Consider the reaction at53°C,where[Fe2+]=3.10molL-1and[Mg2+]=0.310...
Calculate the number of copper ions per gram of copper from the number of copper ions above and the mass of copper ions produced. The mass of the copper ions produced is equal to the mass loss of the anode. (The mass of the electrons is so small as to be negligible, so the mass of...
