2.31×10^(-5) M 1.00 cm 266 nm 0.822

2.31×10^(-5) M 1.00 cm 266 nm 0.822

 

 

The absorbance of a 2.31×10^(-5) M solution of a compound

is 0.822 at a wavelength of 266 nm in a 1.00 cm cell.

Calculate the molar absorptivity at 266 nm.

 

---------------------------------------------------

 

A = ε • C • L = 0.822

( 참고 https://ywpop.tistory.com/12905 )

 

ε = 0.822 / (1.00 cm × 2.31×10^(-5) M)

= 0.822 / (1.00 × 2.31×10^(-5))

= 35584 M^-1 cm^-1

 

 

 

답: 3.56×10^4 M^-1 cm^-1
