50 uL of an aqueous sample of double-stranded DNA is dissolved in 950 uL of water. This diluted solution has a maximal absorbance of 0.326 at 260 nm. What is the concentration of the original (more concentrated) DNA sample, expressed in ug/ul?  I would like to know the process of this question. And I was wondering as well if the total diluted volume would be 950ul + 50ul = 1000ul
