Hey guys, I am having a little bit of trouble. A question gives the Extended Debye-Huckel Limiting Law and asks to solve for the parameter "B". An initial expression obtained for B is pretty easy to formulate, but for the values in the question to be useful in the equation, this initial expression must be changed into a more useful form using other relationships.

In the picture provided I have given the equation of the law, and the initial and rearranged forms for the expression B. Below that are some useful relationships. I feel like I may have overlooked a simple substitution but this is just driving me crazy! Thanks in advance!!!!!
