Answer:
Because it might be reactive or may lose its property in liquid form..
The concentration of solution : 0.2 M

Given
5.6 g Potassium hydroxide(KOH)
500 ml of solution = 0.5 L
Required
The concentration
Solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
MW KOH = 39+16+1=56 g/mol
mol solute(KOH) :
= mass : MW KOH
= 5.6 : 56 g/mol
= 0.1
Molarity :
= 0.1 : 0.5
= 0.2 M
yes i think he is real but it is what you think
Scientist and Chemical Engineers
Molecule is the general term used to describe any atoms that are connected by chemical bonds.
Every combination of atoms is a molecule. A compound is a molecule made
of atoms from different elements.
Well, if a molecule is considered to be a discrete small unit made up of atoms joined
together, then NaCl, and any other ionic solid is not really a molecule. In NaCl we have a
repetitive crystal structure in which each Na+ ion is surrounded by Cl-
ions, and vice-versa, for as far as the crystal extends. There really isn't such a thing
as an NaCl molecule.
