<span>Mol is the unit of amount of substance. It is equal to 6.02 x 10^23 molecules. Now, One mol of Sodium chloride (NaCl) contains 6.022x 10^23 molecules of NaCl. Also, the number atoms of both Na (sodium) and Cl (chlorine) will be equal. Similatly, One mol of Aluminium Chloride (AlCl3) contains 6.022x 10^23 molecules of (AlCl3) but the ratio of Al and Cl atoms will be 1:3</span>
What is the difference between the two numbers? That is your answer
Due to millions of years of spreading the <span>continents will have moved a bit them self on the edges. Erosion will also deform any edge of any continent because its constantly on water and being eroded. </span><span />
