Final answer:
The concentration of DNA in the cuvette is 16.3 µg/mL.
Step-by-step explanation:
The concentration of DNA in the cuvette can be determined using the Beer-Lambert law. The formula for absorbance is A = ε * c * l, where ε is the absorption coefficient, c is the concentration of DNA, and l is the path length. In this case, the absorbance at 260 nm is known to be 0.326, and the absorption coefficient for double-stranded DNA at its max is 0.020 ng µL.
To calculate the concentration in µg/mL, we rearrange the formula as c = A / (ε * l). Plugging in the values, we get c = 0.326 / (0.020 * 1) = 16.3 µg/mL.
