Calculate the concentrations of ion

Question

You have 75.0 mL of a 2.50 M solution of Na₂CrO₄(aq). You also have 125 mL of a 2.50 M solution of AgNO₃(aq). Calculate the concentrations of the following ions when the two solutions are added together.

Na⁺[A] 2.50 M [B] 1.88 M [C] 0.938 M [D] 0 M [E] 5.00 M

CrO₄^2-[A] 0.156 M [B] 0 M [C] 0.188 M [D] 2.50 M [E] 0.938 M

Ag⁺[A] 0 M [B] 1.80 M [C] 0.800 M [D] 1.00 M [E] 1.50 M

NO₃^-[A] 3.13 M [B] 0.313 M [C] 2.50 M [D] 0 M [E] 1.56 M
