This electrochemistry AP Chemistry multiple choice question (MCQ) uses dimensional analysis or conversion factors to determine the amount of time required to electroplate a certain amount of metal. Solving this requires understanding Faraday's constant and amperes, as well as knowing how to convert from grams to moles and how to determine the number of electrons in an oxidation reduction (or redox) reaction. Faraday's constant allows us to convert from moles of electrons to coulombs, and the definition of ampere allows us to convert from coulombs to seconds. This video is particularly to help with the AP Chemistry exam, but it is also useful for other exams and curricula such as the MCAT, DAT, OAT, GRE, SAT, IGCSE, A-levels, JEE, NEET, and CBSE.
