Question

You want to prepare an aqueous antifreeze solution that could go down to ─30 °C. As the antifreeze you use ethylene glycol (EG) (HOCH₂CH₂OH), which has a density of 1.113 g/cm³. In order to prepare 6 L of such an antifreeze solution, how many liters of EG is needed?

(Density of water =1.00 g/cm³, K_f(water) = ─1.86 °C/m, C=12.00, O=16.00, H=1.00 g/mol)
