A liquid-liquid extraction process conducted in Electrochemical Materials Laboratory involved the extraction of nickel from the aqueous phase into an organic phase. A typical set of experimental data from the laboratory is given below. Ni aqueous phase 2.00 2.50 3.00 a (g/l) Ni organic phase 8.57 10.0 12.0 g (g/l) Assuming g is the amount of Ni in the organic phase and a is the amount of Ni in the aqueous phase, the quadratic interpolant that estimates g is given by g = x₁a² + x₂ + x3 Estimate the amount of nickel in the organic phase when 2.83g/1 is in the aqueous phase using the quadratic formula.
