Explanation:
The coefficients are the key.
Create a proportion with them, and the molar mass, and then solve for x:

Answer:
D. ionic bond
Explanation:
Due to electron deficiency in a metal cation, they cannot form a covalent bond beacuse it means to share electrons. By contrast metal cation seek for electrons. In an ionic bond, one atom give electrons, while another atom recevie electron. Because of that, this is the better option to metal cations.
