The concentration of the basic solution is determined by:
N = (number of moles / volume of solution)
number of moles = 1.09 x 10^-2 mol
volume of solution = 1 liter
N of basic solution = 1.09 x 10^-2 mol / 1 liter
N = 1.09 x 10^-2 mol/L
The initial concentration of Zn (OH)2 is 0; the basic solution is 1.09x10^-2 M, then the concentration of OH in the final solution is 1.09x10^-2 M

Because in rock salt, the molecules are packed together and they take longer time to separate and dissolve. As for table salt the molecules are less packed together and take less time to dissolve. Think it like this. The more packed or tightly the substance/object is, the longer it will take for the object to dissolve. The less packed the object/substance is the faster it takes to dissolve. Hope this helped :)
