In another experiment a student makes a voltaic cell using zinc solid metal, zinc sulfate, copper solid metal and copper sulfate, and of course a salt bridge filled with KCl. What voltage would you expect from this cell at room temperature and 1M ZnSO4 solution but 0.01M CuSO4 solution?
1. 0.9816 volts
2. 1.10 volts
3. 1.1592 volts
4. 1.0623 volts
5. 1.0408 volts
