Question

2. What volume (in L) of ethylene glycol must be added to 4.0 gallons of water to obtain a ATr of 20.0°C? 3. Determine the colligative ( effective) molality of a truly saturated salt solution and the freezing point of a truly saturated salt solution. (Solubility limit of NaCl is 35.7g) 4. Compare the answer to #3 to the temperature of y our salt/ice bath. was your salt/ice bath saturated? Explain. 5. Using your temperature for your salt/ice bath and assuming 600ml of water for your saltv/ice bath, calculate the amount in g of salt you added to your salt/ice bath. (Assume the density of water is 1.00 g/ml).

Explanation / Answer

2) 20.0°C / (1.86 °C/m)

=10.75m

(10.75 mol/ kg) × (4.0 gal × 3.78541 L/gal × 1 kg/L) = 162.77mol C2H6O2

(162.77 mol C2H6O2) × (62.07 g C2H6O2/mol)/(1.1132 g/cm3)/(1000 cm3/L) = 9.08 L C6H6O2
