Hello there!
In this case, given those two solutions of aluminum bromide and zinc bromide, it is firstly necessary to compute the moles of bromide ions in each solution as shown below:
Now, we compute the total moles of bromide:
Then, the total volume in liters:
Therefore, the concentration of total bromide is:

Answer:
a.) because your ankle is taking in cold energy from the cold pack
Explanation:
all of the other ones say heat, which is not applied in this question
Answer:
10 M
Explanation:
Molarity -
Molarity of a substance , is the number of moles present in a liter of solution .
M = n / V
M = molarity
V = volume of solution in liter ,
n = moles of solute ,
From the question,
V = 200mL
Since, 1L = 1000mL ,
1 mL = 0.001 L
Hence,
V = 200mL = 0.2 L
n = 2.0 mol
Hence, to calculate the molarity of the solution, the above formula can be used as -
M = n / V
M = 2.0 mol / 0.2 L = 10 M
