Ethylene glycol is a common automobile and antifreeze. What mass of Ethylene glycol must be added to a 10 liter, automobile water cooling system to lower the freezing point to -10 Celsius 
Using Freezing-Point Depression To Find Molecular Weight Name: Nicole Dellicolli Pre-lab questions 1. Ethylene glycol, C₂H6O2, is a common automobile anti-freeze. What mass of ethylene glycol must be added to a 10.0 liter automobile water cooling system to lower the freezing point to -10° C? 2. The boiling point of a solution of 0.402 g of naphthalene, C₁0H8, in 26.6 g of chloroform is 0.455⁰ C higher than the normal boiling point of pure chloroform. What is the boiling-point elevation constant for chloroform? 3. The freezing-point depression constant for mercuric chloride, HgCl2, is 34.3 K/m. A 0.849 g sample of mercurous chloride, HgCl (empirical formula) dissovled in 50.0 g of HgCl, causes a freezing-point depression of 1.24 K. What is the molecular formula for mercurous chloride? [Note: Mercuric chloride, HgCl2, the solvent in this case, is a mercury(II) compound, while mercurous chloride, HgCl, the solute, is a mercury(I) compound.] 53
