As density is an intensive property, it is very useful for identification purposes. Density is also a valuable unit conversion for converting volume to mass or mass to volume. the density of ethanol at 20 c is 0.789g/mL. a) calculate the mass of 25.mL of ethanl. b)Suggest a situation where weighing may be preferable to a volume measurement. c) Calculate the volume of 25.0g of ethanhol. d) Suggst a situation where a volume measurement may be preferable to weighing.
