The standard half-cell potential for the reaction O₂(g) + 4H+ (aq) + 4e¯ → 2H₂O(1) is +1.229 V at 298.15 K. ▼ Calculate E for a 2.00-molal solution of HCl for ao, 1.00 assuming that the ag is equal to the molality. Express your answer to four significant figures and include the appropriate units. E = 1.247 V Submit ✓ Correct Part B Previous Answers Calculate E for a 2.00-molal solution of HCl for ao, = 1.00 using the measured mean ionic activity coefficient for this concentration equal 1.009. Express your answer to four significant figures and include the appropriate units. E 1.247 V Submit Part C Previous Answers ✓ Correct How large is the relative error if the concentrations, rather than the activities, are used? Express your answers in percent to two significant figures.
