When 5.00 mol of benzene is vaporized at a constant pressure of 1.00 atm and at its normal boiling point of 80.1°C, 169.5 kJ are
absorbed and PΔV for the vaporization process is equal to 14.5 kJ.
What is the change of internal energy?
What is the change of enthalpy?
Is the change in entropy positive or negative for this process?
If the pressure would be only ½ atm, what are the changes of internal energy and enthalpy during vaporization (approximately)?
How much energy is absorbed?
Write the definition of the Gibbs Free Energy.
At the lower pressure, will the boiling point be higher or lower.

Answer: The mass of the sample is 1264.800 kg.
Explanation:
Mass of the piece of copper = m
Volume of the copper price =
m = 1,264,800 g = 1,264.800 kg (1 kg = 1000 g)
The mass of the sample is 1264.800 kg.
