cause empirical formular is the elementary or the foundation for molecular formula and molecular formula depends on the empirical formula

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
