Please use word document (nothing handwritten) if citing use ACS style, and for graph use excel only please. If you have any question let me know! The lab is from pg 52-56.

From the Bear’s law: A = ᵋcl
y = 388.4x; 3883.4 = ᵋl
so, ᵋ = 3883.4 M/1 cm = 3883.4 M/cm
[Fe(NO3)3] = 0.02M
[NaSCN] = 0.001M
Volume for NaSCN =1 ML
