Equation: copper and silver acetate --> silver and copper acetate solution
so its Cu + AgCH3COO --> Ag + CuCH3COO right?
Mass of copper: 2.28g
Final mass of copper: 2.01 g (silver formed on it and was removed)
1) Calculate the # of moles of Cu(s) which reacted with the silver ions?
2) How many moles of silver ions were present in the 100-ml sample? What is the concentration of the silver ions in mol/L?
3) What is the concentration of acetate ions present, expressed in mol/L?
I need help solving these because it will be on my test : S thanks in advance!
