A 10.00%-by-mass solution of ethanol, CH 3 CH 2 OH, in water has a density of 0.9831
Question:
A 10.00%-by-mass solution of ethanol, CH3CH2OH, in water has a density of 0.9831 g/mL at 15 °C and 0.9804 g/mL at 25 °C. Calculate the molality of the ethanol–water solution at these two temperatures. Does the molality differ at the two temperatures (that is, at 15 and 25 °C)? Would you expect the molarities to differ? Explain.
