Consider the following anodic (oxidation) reaction in an acidic solution: \(Mg \rightarrow Mg^{2+} + 2e^-\). If 48250 Coulomb charge is produced during this anodic reaction then the amount of Mg (in g) dissolved into the solution is (Given: Faraday Constant = 96500 C/mole of electrons, Atomic weight of Mg = 24)

A fuel with composition by mass is given as 78 % carbon (C), 16 % hydrogen (H2), 3.2 % sulphur (S), 1.6 % oxygen (O2), and ash. The fuel is fired in a boiler with excess air for the complete combustion and no carbon monoxide (CO) is detected in the flue gases. The dry flue gas contains 0.2 % sulphur dioxide (SO2) by volume. Which one of the following options is closest to the amount of excess air provided (in % by mass)?
Assume molar masses (g mol-1) of C, H2, S, and O2 are 12, 2, 32, and 32, respectively, and the volumetric ratio of nitrogen (N2) and oxygen (O2) in the air as 3.76:1.
