Answer is
C. 2.07 M
For explanation
M1V1 = M2V2
M2 = (M1V1)/V2
M2 = (1.5M x 345ml) / 250 ml
:. M2 = 2.07 M

13.- Mg 160 Sb 2.05
14.- Eu 199 Se 2.55
15.- Cs 265 Xe 2.60
The correct answer is evaporation because Vaporization that takes place only on the surface of a liquid is called Evaporation.

Charge ion for Mg is 2+
While 2+ is represents two electrons that had been released. It donors two electrons to oxide ions as oxide ions are 2-. 2- is represents as electron acceptor for two electrons. At the end, the empirical formula for this reaction is Mg2O2
