5.6
= 3.4 X 
Explanation:
the correct answer to it is 3.4 instead of 3.2. I got 3.4 from rounding it from 3.37.
Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.

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.
Lead: Pb, oxygen: O, and silver: Ag
