  • mass Ag deposited = 56g 

  • MM = 107.9 g mol-1 (from Periodic Table) 

  • n (Ag) 56 ÷ 107.9 = 0.519 mol = n(e)



  • n(e) = 0.519 mol 
    F = 96,500 C mol-1

    Q = 0.519 x 96,500 = 50,083.5 C

    Q = 50,083.5 C   I = 4.5 A 


     


    t = Q/I
    t = 50,083.5 ÷ 4.5 = 11,129.67 seconds 
    t = 11,129.67 ÷ 60 = 185.5 minutes 
    t = 185.5 ÷ 60 = 3.1 hours

    WIEGHT DEPOSITED=EQUIVALENT WIEGHT*CURRENT(i)*TIME TAKEN FOR THE DEPOSIT(t)/96500


                AND THUS 45=108*4.5*t/96500

    Diagram is not required to solve this question. You can directly use the formula to find range : R = (v^2/g)*sin2Q Maximum height reached, H = v^2*sin^2Q/2g So, 25 = 40^2*sin^2Q/(2*9.8) So,...
