#40.31# #g*mol^-1#

Explanation:

How did I know this? Well, I have access to a Periodic Table, and you should have access to one as well.

The Periodic Table tells us that the molar mass of oxygen is #15.99# #g*mol^-1#, and the molar mass of magnesium is #24.31# #g*mol^-1#. Sum these masses to get the molar mass of magnesium oxide.

What do I mean by molar mass?
