Question

5. What is the number of ions in solution if 2 molecules of Cr(NO3), completely dissociate?

Answer 1

4

Step-by-step explanation:

This is how Cr(NO3) dissociates

Cr(NO3) --> Cr+1 + NO3-

With one molecule of Cr(NO3), we can see that we have two ions. The question asks for 2 molecules, so it will be 4 total ions.
