Find the EMF of cell (in volts) formed by connected two half cells:   `Pt(s) | MnO_(4)^(-)`(0.1 M), `MnCl_(2)`(0.2M) HCl (1 M)   Pt(s) | `Cr_(2)O_(7)^(2-)(0.1M)` `CrCl_(3)`(0.2M) HCl (0.7 M)`   [Given `E_(MnO_(4)^(-)|Mn^(2+))^(@)` =1.51 V,   `E_(Cr_(2)O_(7)^(2-)| Cr^(3+) = 1.33 V]`   Give your answer by multiplying with 10.
