A voltaic cell consists of a Hg/Hg₂²⁺ electrode (E° = 0.85 V) and a Sn/Sn²⁺ electrode (E° = -0.14 V). Calculate [Sn²⁺] if [Hg₂²⁺] = 0.24 M and E_cell = 1.04 V at 25°C.

The Nernst equation can be used to calculate the concentration of Sn²⁺, given the cell potential (E_cell), the standard cell potential (E_cell°), the Faraday constant (F), and the temperature (T): E_cell = E_cell° - (RT/nF)ln(Q) where Q is the reaction quotient: Q = [Sn²⁺]/[Hg₂²⁺] In this case, n = 2 because 2 electrons are transferred in the balanced equation. Plugging in the values: 1.04 V = (0.85 V) - (0.0257 V)ln([Sn²⁺]/0.24 M) Solving for [Sn²⁺]: [Sn²⁺] = 0.005 M
