Answer:
1.18 V
Explanation:
The given cell is:
Half reactions for the given cell follows:
Oxidation half reaction:
Reduction half reaction:
Multiply Oxidation half reaction by 2 and Reduction half reaction by 3
Net reaction:
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate the EMF of the cell, we use the Nernst equation, which is:
where,
= electrode potential of the cell = ?V
= standard electrode potential of the cell = +1.21 V
n = number of electrons exchanged = 6
Putting values in above equation, we get:
Im pretty sure you do the number times the percentage converted to a decimal and then add the sums so (46*0.706)+(48*0.129)+(50*0.165)
32.476+6.192+8.25
=46.918 amu
*i dont trust my calc so pleasee check if the answer is right and also remember to convert a percent to decimal move the decimal back 2 places so like for 12.9% the decimal is gonna be 0.129
hope this helpss ask if you have questions
