Solving a chemistry problem
201. Antifreezes are solutions with a low freezing point used in the cooling system of cars. Solutions of ethylene glycol C2H4(OH)2 are widely used. At what temperature will such antifreeze freeze if the volume fractions of ethylene glycol and water in it are respectively 0.4:0.6? (For ethylene glycol p = 1.116 g/cm3).
