The density of the resulting solution is extraneous information. It is a result of the two things you put into it, and is not needed.

If you assume the volume of the solution to be 1L since we're calculating molarity (but you can choose any number you want, this is just the easiest).

You have the volume of ethylene glycol in the solution (well, not directly, but they tell you how much with respect to water is in it, so you can calculate it).

You have the density.

How can you use those two values to calculate the mass and moles of ethylene glycol in solution?
