(Answered) 1 determine the amount of heat required to convert 5000 g

Academics

1. Determine the amount of heat required to convert 500.0 g of liquid ethanol at 25.0°C into gaseous ethanol at 125°C. Use the following information on ethanol (C2H5OH) to calculate the amount of heat for each of the steps. Melting Point = -117°C Boiling Point = 78.3°C

Molar Heat Capacities: Csolid =113 J/mol °C Cliquid = 420 J/mol °C ΔHfusion = 5.02 kJ/mol ΔHvaporization = 39.3 kJ/mol

2. Use the following information on Na to determine the total amount of heat required to convert 150.0 g of solid Na at 48.0°C into gaseous Na at 883°C. Melting Point = 98.0°C Boiling Point = 883°C

Molar Heat Capacities: Csolid = 23.7 J/mol °C Cliquid =37.5 J/mol °C ΔHfusion = 2.64 kJ/mol ΔHvaporization = 97.9 kJ/mol
