Mg which stands for Magnesium is the element to begin with, not a compound.
No, water is a compound of hydrogen and oxygen. And filtered sea water would still have many other impurity's in it as well
This depends on the specific element or compound.
yes it does
The answer depends on how many atoms of X and Z are found in each molecule of the compound.
It varies with the compound.
Atoms are the smallest units of an element. Molecules are the smallest unit of a compound.
a compound is made up of a number of different elements. many times carrying some of the characteristics of that element into that compound

Carbon is an element, not a compound. It is a fundamental building block of many compounds, but by itself, carbon consists of only one type of atom.
molar mass of MgCl2= 95.2195.21/125.25=0.76 mole1 mole would have 6.02x1023 formula units so 0.76 moles would have0.76 x (6.02x1023)= 4.575x1023 formula units.
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
