${{K_f}}$ for water is ${1.86\;K\;kg\;{\rm{mo}}{{\rm{l}}^{ - 1}}}$. If your automobile radiator holds 1.0 kg of water, how many grams of ethylene glycol $\left( {{{\rm{C}}_2}{{\rm{H}}_6}{{\rm{O}}_2}} \right)$ must you add to get the freezing point of the solution lowered to ${\rm{ - 2}}{\rm{.8}}^\circ {\rm{C}}$?

A solution containing 1.8 g of a compound (empirical formula $C{H_2}O$) in 40 g of water is observed to freeze at $- 0.465^\circ C.$ The molecular formula of the compound is
