The most pupular electrochemical cell, daniel cell was originally developed by the English chemist john F daniel the general assembly of the cell is as given below An undergraduate student made a Daniel cell using 100cm^(3) of 0.100MCuSO_(4) ad 0.100M ZnSO_(4) solution respectively. The two compartments are connected by suitable salt bridge. [given E_((Cu^(2+)//Cu))^(@)=0.34V,E_((Zn^(2+)//Zn))=-0.76V,(2.30RT)/(F)=0.06,log2=0.3] Q. Calculate the emf (in volt) of the above cell.

A labmate of the student asked her for some solid CuCl_(2) . while she was lifting the bottle from a shelf, the lid of the bottle slipped and some amount of CuCl_(2) fell in the CuSO_(4) compartment at constant volume. She measured the emf of the cell again and found that it has increase by 9 mV. She used this data to calculate the amount of CuCl_(2) that had spilled in the compartment. Calculate the mass of CuCl_(2) that had spilled into the daniel cell? (molar mass of CuCl_(2)=135(g)/(mol))
