Answer: By carrying out series of wet test
Explanation: Dissolve the ionic compound in water. Ionic compounds will ionise and allow the solution to conduct an electric current. Afterwards specific test will be carried out to detect the presence of cations and anions. Another way would be to find the substance's melting point. Ionically bonded compounds have much higher melting points.
density is the kilogram per cubic metre means mass divided by volume.
mathmatically= density= mass/ volume
rough = m/v
Ground cover is the answer
