MgCl2 is the correct formula, or two atoms of Cl for each 1 atom of Mg. You could also say 2 moles of Cl atoms for every 1 mole of Mg atoms. The empirical formula should be written with the subscripts in lowest whole number terms.
Note that this formula is consistent with the fact that an Mg cation is Mg+2 and a Cl anion is Cl-1. Given these charges, a formula of MgCl2 is the one with the smallest whole number subscripts that will allow the charge of the compound to be zero.

What is the chemical formula for Magnesium Oxide?
the final formula of magnesium oxide is MgO.
How many moles of magnesium oxide re formed when 4 moles of magnesium react with oxygen this is the formula for the reaction?
The formula for magnesium oxide is MgO, showing that each formula unit of magnesium oxide contains one mole of magnesium ions. Therefore, if there is ample oxygen available, 4 moles of magnesium will form 4 moles of magnesium oxide.
What type of oxide is magnesium oxide?
The answer is in the question. Magnesium is an element, so is oxygen, together they can form MgO, a compound, as compounds are multi atomic structures, like Iron Oxide, another rust just like MgO.
