Question

Given the following data, calculate the heat (q) transferred into/out of the system when 100 g of carbon tetrachloride (CCl?) freezes at its normal melting point. Include the correct sign of q for this process. MW (g/mol) | ?Hfus (kJ/mol) | ?Hvap (kJ/mol) Benzene | 78.108 | 9.821 | 30.768 Carbon Tetrachloride | 153.81 | 2.680 | 29.890 12.57 -12.57 1.742 -1.742 19.43 -19.43

Step 1

Given: - Molecular weight of carbon tetrachloride (CCl4) = 153.81 g/mol - Mass of carbon tetrachloride = 100 g Number of moles = Mass / Molecular weight Number of moles = 100 g / 153.81 g/mol Number of moles = 0.650 moles ** Show more…
