Final answer:
The boiling point of ethanol at 50 kPa will be lower than its standard boiling point of 78.37 °C and somewhere between 20.0 °C and 63.5 °C.
Step-by-step explanation:
The boiling point of ethanol varies depending on the ambient pressure. At standard atmospheric pressure (101.3 kPa), pure ethanol has a boiling point of 78.37 °C. However, at a reduced pressure of 50 kPa, the boiling point of ethanol will be lower than this.
We do not have specific data for ethanol's boiling point at exactly 50 kPa in the information provided, but we can infer that the boiling point will be somewhere between 20.0 °C and 63.5 °C since at 5.95 kPa, the vapor pressure corresponds to a temperature of 20.0 °C and at 53.3 kPa to a temperature of 63.5 °C. By plotting the vapor pressure vs. temperature graph, we can estimate the boiling point at 50 kPa. Based on the graph, the boiling point of ethanol at 50 kPa would be between 25 °C and 30 °C.
