Question

Calculate the enthalpy change of vaporisation of benzene if 13 gram of benzene vaporised by supplying 5.1 kJ of heat.

• A. \( 43.5 \text{ kJ mol}^{-1} \)
• B. \( 35.3 \text{ kJ mol}^{-1} \)
• C. \( 30.6 \text{ kJ mol}^{-1} \)
• D. \( 40.7 \text{ kJ mol}^{-1} \)

Hint:

Always convert the given mass to moles first to find molar enthalpy values.
