New to chemistry, and have no clue how to start on the following problem:
An electric current of 10.0 amperes is passed through a solution of gold (III) chloride for a period of 0.500 hours. After this period of time, how much gold has plated out on the cathode? There are 96,500 coulombs/mol of electrons. A mol of gold has a mass of 197 g/mol. An ampere is equal to 1 coulomb/second. It is necessary to transfer 3.00 mol of electron/mol gold.
Any assistance would be appreciated!
