Really need help with a Chemistry Question?

Glycerol,C3H8O3 (92g - m), is a water-soluble liquid with a density of 1.2656 g/mL at 15�C. Calculate the molarity of a solution of glycerol made by dissolving 50.000 mL glycerol at 15�C in enough water to make 250.00 mL of solution. What is the answer, thank you so much??
