Solution.
“2.25 ppm = 2.25 times 10^{-3} g/L”
“Cm = frac{m}{M times V}”
“Cm = frac{2.25 times 10^{-3}}{166.2} = 1.35 times 10^{-5} M”
“A = xi times l times Cm”
“xi = frac{A}{l times Cm}”
“A = lg[frac{I0}{I}]”
“A = lg[frac{100}{37.5}] = 0.426”
“xi = frac{0.426}{1 times 1.35 times 10^{-5}} = 3.16 times 10^4 frac{L}{mol times cm}”
Answer:
“xi = 3.16 times 10^4 frac{L}{mol times cm}”
