Could someone explain how to do part b? Because it is asking for Kb and pKb is it an acid or a base?

It's asking for the dissociation constant of the base. Because its pH is greater than 7, the compound is basic. You have to find the Ka, then divide Kw by Ka to find Kb

It is a base so you need to find the pOH from the pH. Using the pOH, you can then find the concentration of OH- and from that calculate Kb.

oh ok thanks so much!
