A chemist prepares a mixture of ethanol and water at a temperature of 23.0 °C. He measures out 38.5 mL of ethanol and mixes it with 38.2 mL. He measures the volume of the solution after it is well mixed and finds that it is 73.6 mL. The density of ethanol is 0:79 g/mL and the density of water is 1.0 g/mL. Calculate the volume percent of ethanol in this solution. Be sure your answer has the right number of significant digits. db
