Question

QUESTION 7 4 poi Let's say the molarity of your original solution is 0.0380 molar Cu2+.! Let's say you will dilute this solution by adding 18.0 mL of the solution to a 200.0 mL volumetric flask and adding water to the mark. What is the new molarity? QUESTION 8 4 pol What color light does Cu(NH3)4+2 absorb? Hint, read guide to lab on Blackboard and look at color vs wavelength Blue green indigo violet red

Answer 1

Question - 1 MiVi= M2 V2 m, and vi are initial concentration and volume respectively while M2 and 12 are final concentration and volume respectively. Mi = 0.0380 M M2=2 VI= 18.0mL V2 = 200.0 mL M2 = Milli = 0.0380 M X 18.0m2 = 3.42X10-3M V2 200.0mL Hence, the new molarity is 3.42 X 16-3M Kindly post different questions separately. Please Rate.
