Final answer:
The line structure implies eight carbon atoms and sixteen hydrogen atoms, corresponding to a molecular formula of C8H16 for the organic molecule.
Step-by-step explanation:
In the line structure of an organic molecule, each line's end or intersection represents a carbon atom, and it's understood that each carbon must have four bonds in total. If not enough lines (bonds to other carbons) are shown, the remaining bonds are to hydrogen atoms, which are often not drawn. Therefore, with eight carbon atoms, we calculate the number of hydrogens as needed to complete the four bonds for each carbon. In this case, the molecule has 16 hydrogens, giving us a molecular formula of C8H16.
The correct question is How many carbon atomes and how many hydrogen atoms are present in the first line structure pictured?....../.;
