If 8.70 g of CuNO3 is dissolved in water to make a 0.170 M solution, what is the volume of the solution in millimeters?

I know that I have to first get the molar mass of CuNO3 and then divide that by the solution, but I'm not sure what to do after that. What would be the next step? Would I have to do something with the water that is being used?

The first step would be to divide the 8.70 grams of CuNO3 by its molar mass to obtain the amount of CuNO3 in moles. Next, you should divide the moles of CuNO3 by molarity of the desired solution (0.170 M). This will give you the volume of the solution in liters.
