    I'm stuck! Boiling point elevation problem

    I am at a loss for what to do with this problem: Determine the molality of a 100.0-mL water sample to which antifreeze (ethylene glycol, C2H6O2) has been added, if the boiling point of the solution rises to 104.5°C. From the molality, determine the number of grams of ethylene glycol added to...

    Stuck on Analytical Chemistry Problem

    Hi all, I'm stuck. Here's the question. Calculate the electrode potential of a platinum electrode immersed in a solution that is, .075 M in Fe2(SO4)3 and .06 M in FeSO4? It seems to me this is a cell where Fe2+ gets oxidized to Fe3+ and Sulfate gets reduced to H2SO3. Thus, anode...
