Dear tees;

Without additional information you have at least three possible results!
Is there a structure formula or something else?

Good Luck!

Dear tees;

So search Wiki for the density of Acetone, convert the volume into mass, and finally translate the mass into moles with the help of molecular weight of Acetone.

Good Luck!

Dear tees;

If I interpret your reaction correctly then I have to tell you that the forum does NOT make your or others home work, see   "Forum Rules" (4.)
The Forum only helps by directing you to the correct way to the solution.

So you will have to search Wiki (Wikipedia) for the density and think about how you have to convert the given volume into a mass.
Additionally I hope you know what the Molecular Weight of Acetone is, and what its meaning is, otherwise you may also ask Wiki about.

Good Luck!
