Incorrect Question 5 Calculate The New Boiling And Freezing Temperatures Of 4451 G Water When 1 01 Kg Of Ethylene Glycol 1 (300.08 KiB) Viewed 9 times
Incorrect Question 5 Calculate the new boiling and freezing temperatures of 4451 g water when 1.01 kg of ethylene glycol (antifreeze, C₂H602) is added. enter answer with correct sig figs, no unit [NOTE: watch sig figs in mixed math!] Tbp pure water = 100.0°C Kbp= 0.512 °C/m Kfp = 1.86 °C/m Molar mass of ethylene glycol = 62.07 g/mol new boiling point 225. new freezing point 454. Tfp pure water = 0.00 °C °C 0/1.5 pts °C
Incorrect Question 4 What is the energy involved to heat a 78.5 g sample of liquid ethyl acetate (C4H80₂) from 25.6 °℃ to 93.4 °C? Report your answer with correct unit and sig figs Constants: Enthalpy of fusion (AHfus, deltaHfus): Enthalpy of Vaporization (AHvap, deltaHvap): Specific Heat Capacity, liquid (Cliq): Specific Heat Capacity, gas (Cgas): Molar mass of ethyl acetate: 88.11 g/mol Point (T): 77.5 °C 0/2 pts 10.1x10^3 J 10.48 kJ/mol 365.7 J/g 1.904 J/(g°C) 125.8 J/(mol K) Boiling
