Three 50.0 mL samples of ethanol are each maintained at the following conditions:
• Sample 1: solid ethanol at −120 °C
• Sample 2: liquid ethanol at 25 °C
• Sample 3: ethanol vapor at 78 °C and 1 atm
Which of the following correctly ranks the three samples by density, from greatest to least?
a) Sample 2>Sample 1>Sample 3
b) Sample 1>Sample 3>Sample 2
c) Sample 1>Sample 2>Sample 3
d) Sample 2>Sample 3>Sample 1
