Answer:
A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and strong) acid. A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself.
Explanation:
Concentrated acid - Those acids which are pure or have very high concentration in water are called as concentrated acids. For example concentrated Hydrochloric acid (HCl) and concentrated Sulphuric acid are examples of concentrated acids.

Answer:
The answer to your question is Tb = 100.768°C
Explanation:
Data
Tb = ?
moles of KBr = 3
mass of water = 2000 g
Kb = 0.512 C/m
Process
1.- Calculate the molality of the solution
molality = moles of solute/mass of solvent (kg)
-Substitution
molality = 3/2
-Result
molality = 1.5
2.- Calculate ΔT
ΔTb = Kbm
-Substitution
ΔTb = (0.512)(1.5)
-Result
ΔTb = 0.768
3.- Calculate the boiling point, the boiliing point of pure water is 100°C
ΔTb = Tb - Tb(solvent)
-Solve for Tb
Tb = Tb(solvent) + ΔTb
-Substitution
Tb = 100 + 0.768
-Result
Tb = 100.768°C
