1 mol = 6.023 x 10^23 particles .............. so a nanomol = (6.023 x 10^23) x 10^-9 = 6.023 x10^14 particles using W =( ne x V) for work done by field on the charge n = 835 x 6.023 x 10^14 electrons e = 1.6 x 10^-19 C (electron charge) V = 2.3V W = 835 x 6.023 x 10^14 x 1.6 x 10^-19 x 2.3 = 0.1851J (answer)
