SUMMARY
The discussion focuses on calculating the heat released during the condensation of 15.8 g of methanol (CH3OH) at 25°C, utilizing the heat of vaporization (ΔHvap) of 38.0 kJ/mol. To determine the heat released, participants emphasize the need to convert grams of CH3OH to moles using its molar mass, which is approximately 32.04 g/mol. The calculation involves using the formula Q = n × ΔHvap, where Q is the heat released, n is the number of moles, and ΔHvap is the heat of vaporization. The final result indicates that 15.8 g of CH3OH releases approximately 19.0 kJ of heat upon condensation.
