A student dissolves 2.2 g of urea CO in 175. mL of a solvent with a density of 0.89 g/mL. The student notices that the volume of the solvent does not change when the urea dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity = molality
