The coolant in automobiles is often a 50/50 % by volume mixture of ethylene glycol,HOCH2CH2OH,and water.At 20°C,the density of ethylene glycol is 1.1088 g/mL and the density of water is 0.9982 g/mL.Assuming that the volumes are additive,what is the expected freezing point of a 50/50(v/v) % ethylene glycol/water solution? Kf = 1.86°C/m for water.
A) -16°C
B) -17°C
C) -30°C
