<u>Answer</u>
Rise: The kingdom of D'mt populated the majority of the Northern horn which had developed much agriculture and expansion of trade with other empires like Egypt. After the fall of the D'mt kingdom many small kingdoms took its place and slowly came together as one large kingdom called, Aksum. Aksum rose to power in the first century after the son of a Solomon queen had expanded to the land near the red sea.
Fall: The empire had become isolated from civilizations when it came to trade after battling Arabian armies. Their religion segregated them and caused the downfall of their power over the trading ports on the Red Sea.

5.367 ml of the concentrated acid must be added to obtain a total volume of 100 ml of the dilute solution.
Dilution is defined as the process in which the concentration of a sample is decreased by adding more solvent. The dilution formula is given below.
C₁V₁ = C₂V₂
where C₁ = initial concentration of sample = 3.00 m
V₁ = initial volume of sample
C₂ = final concentration after dilution = 0.161 m
V₂ = total final volume after dilution = 100 ml
Plug in the values to the formula and solve for the volume of the concentrated acid that must be added.
C₁V₁ = C₂V₂
3.00 m (V₁) = 0.161 m (100 ml)
V₁ = 5.367 ml
