A lithium salt used in lubricating grease has the formulaLiCnH2n + 1O2. The salt is soluble in water to the extent of0.036 g per 100 g of water at 25 °C. The osmotic pressure ofthis solution is found to be 57.1 torr. Assuming that molalityand molarity in such a dilute solution are the same andthat the lithium salt is completely dissociated in the solution,determine an appropriate value of n in the formulafor the salt.

Question
A lithium salt used in lubricating grease has the formula
LiCnH2n + 1O2. The salt is soluble in water to the extent of
0.036 g per 100 g of water at 25 °C. The osmotic pressure of
this solution is found to be 57.1 torr. Assuming that molality
and molarity in such a dilute solution are the same and
that the lithium salt is completely dissociated in the solution,
determine an appropriate value of n in the formula
for the salt.
