Protons have a mass of 1
Neutrons have a mass of 1
So 13*1 + 14*1 = Mass number 27

Answer:
See explanation
Explanation:
Anode;
Sn(s) ------> Sn^2+(aq) + 2e
Cathode;
Mn^2+(aq) + 2e ------> Mn(s)
The minimum voltage required to drive the reaction is the cell voltage. The cell voltage is obtained from;
E°cell= E°cathode - E°anode
E°cell= -1.19 - (-0.14)
E°cell= -1.05 V
The concentration of a substance is the quantity of solute present in a given quantity of solution.
