The structural formula shown in the picture is the cyclic AMP or cyclic adenosine monophosphate. It is an essential component in RNA synthesis and metabolic processes. When it becomes non-cyclic after enzymatic reaction, you would have to disconnect the cyclic rings. When you do, you add 2 H atoms, one for each terminal end. The formula for cyclic AMP is C₁₀H₁₄N₅O₇P. Since there are three cyclic rings, you would have to add 6 hydrogen atoms.
Thus, the formula for noncylic AMP is C₁₀H₂₀
N₅O₇P.

basically, if its on the periodic table, its an element. for example, rock can be made of many things in the periodic table, therefore its a compound. salt, is NaCl, which are two elements put together, therefore its a compound.
The two volumes are taken as additive ( in actuality they will not be) , then Final volume = 39.5+215 = 254.5mL % v/v ethanol = 39.5/254.5*100 = 15.5%l
