What is the energy change (in kJ) when 0.487 kilograms of diethyl ether (C4H10O) is condensed from a gas at 34.6°C (its boiling point) to a liquid at the same temperature? The ΔHvaporization for diethyl ether = 26.0 kJ/mol.
Diethyl ether has a molar heat of vaporization of 26.5 kJ/mol and a normal boiling point of 34.6 °C. What is the vapor pressure of diethyl ether at 10.0 °C?
The familiar "ether" used as an anesthetic agent is diethyl ether, C4H10O. Its heat of vaporization is +26.5 kJ/mol at its boiling point. (Figure 1) How much energy (in kilojoules) is required to convert 235 mL of diethyl ether at its boiling point from liquid to vapor if its density is 0.7138 g/mL?
This question asks: Calculate the change in entropy that occurs in the system when 1.00 mol of methanol (CH3OH) vaporizes from a liquid to a gas at its boiling point (64.6 degrees Celcius). For methanol, enthalpy of vaporization = 35.21 kJ/mol I'm getting the correct answer (104) but I'm getting a negative for some reason, and the book says it's positive, but the formula changeinEntropy = -enthalpy of system/T, so why isn't this number negative?
2. What is the change in entropy in the system when 4.50g of ethanol (CH3CH2OH) condenses to liquid at its normal boiling point of 78°C? The heat of vaporization for ethanol is 38.56kJ/mol.
