Answer : The concentration of guanosine in your sample is, [tex]8.33\times 10^{-5}M[/tex]
Explanation :
Using Beer-Lambert's law :
[tex]A=\epsilon \times C\times l[/tex]
where,
A = absorbance of solution = 0.70
C = concentration of solution = ?
l = path length = 1.00 cm
[tex]\epsilon[/tex] = molar absorptivity coefficient guanosine = [tex]8400M^{-1}cm^{-1}[/tex]
Now put all the given values in the above formula, we get:
[tex]0.70=8400M^{-1}cm^{-1}\times C\times 1.00cm[/tex]
[tex]C=8.33\times 10^{-5}M[/tex]
Thus, the concentration of guanosine in your sample is, [tex]8.33\times 10^{-5}M[/tex]
