In cold climate, water in a car radiator freezes and causes damage. Ethylene glycol is used as an antifreezing agent. The amount of ethylene glycol that should be added to $$5\ \mathrm{kg}$$ of water to prevent freezing at $$-7^\circ\mathrm C$$ is, given $$K_f=1.86\ \mathrm{K\,kg\,mol^{-1}}$$ and molar mass of ethylene glycol $$62\ \mathrm{g\,mol^{-1}}$$

A

$$1165\ \mathrm g$$

B

$$46.7\ \mathrm g$$

C

$$116.7\ \mathrm g$$

D

$$93.4\ \mathrm g$$
