For the reaction 2Co3+(aq)+2Cl−(aq)→2Co2+(aq)+Cl2(g) . E∘=0.483 V what is the cell potential at 25 ∘C if the concentrations are [Co3+]= 0.136 M , [Co2+]= 7.80×10−2 M , and [Cl−]= 0.841 M , and the pressure of Cl2 is PCl2= 6.60 atm ? Express your answer with the appropriate units. View Available Hint(s) E = nothing nothing

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
