°C) can be calculated using the following equation:
ΔHvap = n × ΔHvap,m
where ΔHvap is the molar enthalpy of vaporization, n is the number of moles of substance being vaporized, and ΔHvap,m is the molar enthalpy of vaporization per mole of substance.
The molar enthalpy of vaporization of benzene is 30.8 kJ/mol at its boiling temperature of 80°C.
Therefore, the change in enthalpy when 3 mol of liquid benzene transforms to the vapor state at its boiling temperature is:
ΔHvap = 3 mol × 30.8 kJ/mol
ΔHvap = 92.4 kJ
So the change in enthalpy is 92.4 kJ.
ΔHvap = n × ΔHvap,m
where ΔHvap is the molar enthalpy of vaporization, n is the number of moles of substance being vaporized, and ΔHvap,m is the molar enthalpy of vaporization per mole of substance.
The molar enthalpy of vaporization of benzene is 30.8 kJ/mol at its boiling temperature of 80°C.
Therefore, the change in enthalpy when 3 mol of liquid benzene transforms to the vapor state at its boiling temperature is:
ΔHvap = 3 mol × 30.8 kJ/mol
ΔHvap = 92.4 kJ
So the change in enthalpy is 92.4 kJ.
