What mass of copper will be deposited by a current of 7.89?
7.89 what
7.89 AMPERES
To determine the mass of copper deposited by a current, we need more information. Specifically, we need to know the time for which the current flows and the efficiency of the electroplating process, as not all of the current may be used to deposit copper. Additionally, we require the molar mass of copper to convert the amount of charge passing through the circuit into the mass of copper deposited.
Without these details, we cannot proceed with calculating the mass of copper deposited accurately.
