PLEASEE ANSWER ALL AS THEY ARE CALCULATED TOGETHER BUT DIFFERENT QUESTIONS. I REALLY NEED HELP AND I WILL DEFF CONSIDER THUMBS UP

Part A A voltaic cell consists of a Zn/Zn²+ half-cell and a Ni/Ni²+ half-cell at 25 °C. The initial concentrations of Ni²+ and Zn2+ are 1.80 mol L¬1 and 0.120 mol L, respectively. What is the initial cell potential? Zn²+(aq) +2 e → Zn(s) Ni²+ (ag) + 2 e → Ni(s) E° = -0.76 V Express your answer to two decimal places and include the appropriate units.
