### Chem/Orgo Book Pg. 162, Q7

I was hoping someone could provide some clarification for the explanation for questions 7 from the practice passage. I've read through the work and looked back in the chapter where it talks about normality. I understand how 100 ml of RbOH was determined, but can't figure out how the mass was determined using the formula NaVa=NbVb. Also, how would we know the gram equivalent weight of RbOH is 102g/equiv? Thanks!
