Calculate the power output of a galvanic cell given that the cell potential is 1.8 V and the current passing through the circuit is 2.5 A. The electrochemical reaction taking place in the cell is the oxidation of Zinc and reduction of Copper. The standard reduction potentials are +0.76 V for copper and -0.76 V for zinc. The concentration of Zinc ions is 1.0 M whereas Copper ions concentration is 0.1 M. Determine the power output of the cell.
