Answer to Question #160942 in General Chemistry for Mohd irfan

Question

Anorganic compound has wavelength max = 480nm. The absorbance

of it solution was found to be 0.560. If an unknown

solution of this

of this compound gave

an absorbance of 0.750

calculate the concentration​

Answer 1

$y=mx + b$

Y=0.750

X= concentration

m=480×10^-9

b=0.56

mx=0.75- 0.56= 0.19

X=0.19/480×10^-9

x= 3.96×10⁵
