density= mass/volume
we need the volume of the metal to find the density, in which case the answer would be 64.2/volume=density

Answer : The given statement is, false.
Explanation :
Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.
The mathematical expression will be,
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be,
. And the pH of the solution is, 7.
When the concentration of hydrogen ion is greater than
then the solution is acidic in nature. And the pH of the solution is, less than 7.
When the concentration of hydrogen ion is less than
then the solution is basic in nature. And the pH of the solution is, greater than 7.
Hence, the given statement is false.
