Answer:
If you want the first option you need 2.5M.
If you want the second, you will end up with 120ml so your starting solution is:

Answer:
178.1g
Explanation:
m= n × MM
where
m is mass
n is moles &
MM is molecular mass
The molecular mass of cobalt is 58.933195. With this information and the number of moles given in the question, we can perform the calculation
m= 3.022 × 58.933195
m=178.09611529
m= 178.1g
