Molarity is defined as the moles of solute per liter of solution.
. Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of
which is 109.98 g/mol


Then we find the molarity using above equation

The two s Orbital electrons and one d orbital electron, are the electrons that are lost by an atom of Iron when it forms the Fe3 + ion.
It creates chlorofluorocarbons(CFCs) also would create biooxygen but in the multiple choice it only shows the CFCs
Movement of molecules from an area of higher concentration to one of lower concentration is called Diffusion
