When expressing the correct number of significant figures in addition, you go to the last common decimal place. In this case that is 0.1 because all the numbers have this decimal place.
This is because your measurement can only be as precise as the least precise measurement. The more decimal places in the measurement, the more precise the measurement.
mol CO₂ = 9.6
mol N₂ = 4.8
mol O₂ = 0.8
mol H₂O = 8

Answer:
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current. But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.
