1. The problem statement, all variables and given/known data What is the Molarity of 70% TBHP? 2. Relevant equations Given: d=.937g/ml, FW=90.12g , w/w%? 3. The attempt at a solution 1000mL x (0.937g/mL) x (1mol/90.12g) = 10.4M That is what I got but idk what to do with the 70% or that w/w% or is that right the way I did it?
