One half-cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknonw concentration. It other half cell consists of a zinc electrode dipping in 1.0M solution of `Zn(NO_3)_2`. A voltage of 1.48V is measure for this cell. Use this information to calculate the concentration of silver nitrate solution used `(E_(Zn^(2+)//Zn)^0=-0.76V,E_(Ag^+//Ag)^0=+0.80V)`
