0.020 = 0.12 - (2.303*8.314*298)/(2*96485)*log[((1)(0.27))/((1)(x))] x= 0.000112046 or 1.12046*10^-4 Molarity It looks correct
temp 298 log is base 10 Ecell = Eo cell - (0.0592/2) log Keq (from step above). .020=.12-(0.0592/2)log Keq log(.27/m) 0.02 = 0.12 - 0.0128551 log(0.27/m) m=0.000112976 SEEMS LIKE A SMALL AMOUNT. HOW DO I CHECK??
