For the cell

is 1.10 V. A student prepared the same cell in the lab at standard conditions. Her experimental was 1.0 V. A possible explanation for the difference is that

(a) a larger volume of Zn²⁺ than Cu²⁺ was used.

(b) the zinc electrode had twice the mass of the copper electrode.

(c) [Zn²⁺] was smaller than 1 M.

(d) [Cu²⁺] was smaller than 1 M.

(e) the copper electrode had twice the surface area of the zinc electrode.
