Answer:
See explanation
Explanation:
In this case, we have to remember the meaning of the nomenclature "18:2Δ9,12". Where 18 is the <u>number of carbon atom</u>s, 2 is the <u>number of double bonds,</u> and the numbers successive to Δ "delta" the position of the double bonds <u>starting</u> to count from the carboxylic -COOH end of the molecule.
In other words, the main functional group is a <u>carboxylic acid</u>. We have a total of 18 carbons. Additionally, we have 2 double bonds. On carbons 9 and 12.
Lets see figure 1

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
Lithium is a metal and Fluorine is a non-metal, which means they will form an ionic bond. An ionic bond is when a metal atom donates its electron complete to a non-metal atom.
Sulphur is found in 23 isotopes ranging from 27 to 49.
Also, magnitude of average atomic mass is more toward the isotope which is the most abundant.
Now , molecular mass of Sulphur is 32.06 u . It means the most abundant isotopes of Sulphur is 32.
It can also be verified by the fact that 95 % of natural occurring sulfur is 
.
Hence, this is the required solution.
