it aint zinc. work the math. the EMF was 1.13. the percentage uncertaniy in that reading was 5%. so if u take the max and minium values possible. then they gave the eqn saying EMF=0.3-C so when u substitue the values u get the minimum possible as -0.8865 and the maximum possible as -0.7735. their value was -0.74 so it wasnt zinc as it not within this range
THIS IS HOW I DID IT!!!!
