Answer:
1.7 Osm/L
Explanation:
Osmotic concentration is the number of osmoles (Osm) of solute per litre of solution .
An osmole is the number of moles of solute that contribute to the osmotic pressure of a solution.
1 Osm = i × n, where
i = the van't Hoff i factor and
n = the number of moles
The van't Hoff i factor is the number of solute particles obtained from 1 mol of solute.
For example,
MgSO₄(aq) ⟶ Mg²⁺(aq) + SO₄²⁻(aq)
1 mol of MgSO₄ produces 2 mol of ions in solution, so i = 2.

Explanation:
We know that the cis isomer has more heat of hydrogenation since it is less stable than the trans isomer. Since the hydrogenation of both compounds yields the same product and the hydroboration/oxidation both give a primary alcohol, they are geometric isomers and Y is the trans isomer (Image 2).
For the compound C8H12, the compound in question must be 1,5- cyclooctadiene since two moles of the same aldehyde was obtained after ozonolysis and reaction with two equivalents of hydrogen gives cyclooctane (Image 1).
