Calculate the molarity of a solution in which 0.75 moles of a solute are dissolved in 125g of solution (density of solution = 1.05g/mL).

I don't even know where to begin.

Start with the definition.

Molarity=molesSolute/volumeSolution

and VolumeSolution=masssolution/density.

You will have to change the volume from ml to Liters.

1.05 * 1L/1000mL = 0.001 L

So, do I then go ahead and do this:

Vsolution = 125g/0.001 L ?
