It's MgO. Molarity is defined as mols solute/L solution.
If you want 2.5 L of 0.5 M solution, then you want how many mols? That's mols = M x L = ?.
Then how many grams do you need? That's mols = g/molar mass. You know molar mass (or can calculate it) and you know mols. Substitute and solve for grams MgO. Post your work if you get stuck.
