Correct the grammar and remove unnecessary words to get: Calculate the cell voltage: Zn | Zn^2+ (10M) || Cu^2+ (0.20M) | Cu.

Calculate the cell voltage: Zn | Zn^2+ (1.0M) || Cu^2+ (0.20M) | Cu.
Extra: The provided text seems to be describing a galvanic cell involving zinc and copper. In electrochemistry, galvanic cells, also known as voltaic cells, convert chemical energy into electrical energy through spontaneous redox reactions.
The corrected text is a shorthand notation for representing the cell. Each half-cell is separated by a single vertical line (|), which represents a phase boundary (for example, between a solid electrode and an aqueous solution of ions). The double line (||) stands for the salt bridge or porous membrane that separates the two half-cells while allowing ions to flow between them, which is necessary to maintain electrical neutrality in the system.
The substances involved in the reaction are represented by their chemical symbols, with metals given as solids (Zn, Cu) and ions in solution indicated along with their molarities (Zn^2+ (1.0M), Cu^2+ (0.20M)).
The notation provided is part of the calculation for determining the cell potential, which is the measure of the cell's ability to produce an electric current. The cell potential can be calculated using the Nernst equation, given that the standard reduction potentials of the electrodes are known and the concentrations of the ions are provided. The molarity (M) is a unit of concentration that reflects the number of moles of a substance per liter of solution, therefore it is essential to ensure that these values are included and correct in the notation.
