SUMMARY

The discussion focuses on calculating the formula weight of the copper ammine complex, represented as [Cu(NH3)x]SO4*H2O. Participants clarify that to determine the molecular weight, one should consider various integer values for X, where X represents the number of ammonia (NH3) molecules coordinating to the copper (Cu) ion. The approach involves experimentally determining the mass of the complex for different X values, specifically X = 1, 2, etc., to derive the corresponding formula weights.

PREREQUISITES
  • Understanding of molecular weight calculations
  • Familiarity with coordination chemistry
  • Knowledge of the copper ammine complex structure
  • Basic skills in experimental mass measurement
NEXT STEPS
  • Research the molecular weight calculation for coordination compounds
  • Learn about the properties of copper ammine complexes
  • Explore experimental techniques for measuring complex masses
  • Study the implications of varying X values in coordination chemistry
USEFUL FOR

Chemistry students, researchers in coordination chemistry, and anyone involved in the study of metal complexes and their properties.

I don't really know where to start with this, here's 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?

Thx!

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.)
