A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded. A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.

this question quite easy if you no lost any part..

so as Hg is 200 and O is 16 so HgO is 216 g per mole ; if you have 108 g of Hgo you have 0.5 mole so this will give 100 g of mercury..

note that if you realy do, you should take care in very well ventilatate place, better under a laboratory hood because those vapors are highly toxic in long term..
