Final answer:
The concentration of the zinc bromide solution is 0.1 g/mL.
Step-by-step explanation:
To calculate the concentration of zinc bromide, we need to divide the mass of zinc bromide by the volume of the solution.
The concentration formula is:
Concentration (C) = Mass of Solute (m) / Volume of Solution (V)
In this case, the mass of zinc bromide is given as 250.0 grams and the total volume of the solution is 2.5 liters (or 2500 mL).
Plugging these values into the formula:
C = 250.0 g / 2500 mL = 0.1 g/mL
Therefore, the concentration of the zinc bromide solution is 0.1 g/mL.
