Homework Help: Calculate the formula weight for values of X

  1. Mar 22, 2007 #1
    I don't really know where to start with this, heres the question

    the general formula for the copper ammine complex is [Cu(NH3)x]SO4*H2O

    calculate the formula weight for several X values of X.(What are reasonable values for x?)

    Do i just plug in random #s for X and figure out the molecular weight?

    I pressume that you want to know how many NH_3 molecules that coordinates to Cu - so assume that you are able to experimentally get the mass of the complex than you can determine X - so calculate the mass of the complex by using X = 1,2.....

    (Or at least that is how I understand your exercise.)
