Answer:

One equiv of silver ion, #Ag^+#, and half an equiv of #MgCl_2(aq)#.

Explanation:

And how do we know? Well, if we write the stoichiometric equation we have illustrated the stoichiometry:

#2AgNO_3(aq) + MgCl_2(aq) rarr Mg(NO_3)_2(aq) + 2AgCl(s)darr#

Alternatively, we could write the net ionic equation...........

#Ag^(+) + Cl^(-) rarr AgCl(s)darr#

Given the stoichiometry, #(0.276*mol)/2# #MgCl_2# were used..
