This depends on the specific element or 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
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.

Mg which stands for Magnesium is the element to begin with, not a 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 formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
