Answer:

Formula of magnesium oxide is MgO and formula of strontium oxide is SrO

Step-by-step explanation:

Ca, Mg and Sr are same group bivalent metals.

Oxygen is a bivalent element

In general, formula of a compound made of a cation
M^(x+) and an anion
A^(y-) is
M_(y)A_(x) for
$x\\eq y$

When x = y, formula of the compound becomes MA

As both these metals and oxygen are bivalent therefore formula of magnesium oxide is MgO and formula of strontium oxide is SrO.
