Let <span>A= ebc </span>
<span> 0.765 = 86,300*1.3*c </span>
<span>
Solve for c = approximately 7E-6 Molar
= mols/L soln. </span>
<span>g = 7E-6*893.49
= about 0.006 g chlorophyll/L soln. </span>
<span>
1000 x 0.785 = 785 g ethanol. </span>
<span>Conc. = about 0.006g chlorophyll/785 g soln. </span>
<span>
Change that to ppm. by using formula:
(0.006/785)*1E6</span>

Answer:
2-hexanone
Explanation:
Since we are asked to find the IUPAC Name;
First thing we need to do is to identify the functional group.
In this case it is ketone group, because the formula for ketone is CnH2nO.
Thus, the last suffix will be -one.
Secondly, secondly, we will find the longest carbon chain which in this case is 6. Six has the prefix "hex-"
The Formula has no branches group.
Thus, we can call it 2-hexanone
