A student dissolves 6.2 g of biphenyl (C12H10) in 400. ml of a solvent with a density of 0.83 g/ml.. The student notices that the volume of the solvent does not change when the biphenyl dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits.
