Chemistry - Liquid Solution Question with Solution | TestHub

${\mathrm{K}}_{\mathrm{f}}$ for water is $1.86\mathrm{K}\mathrm{kg}{\mathrm{mol}}^{-1}$. If your automobile radiator holds $1.0\mathrm{kg}$ of water, how many grams of ethylene glycol $\left({\mathrm{C}}_2{\mathrm{H}}_6{\mathrm{O}}_2\right)$ must you add to get the freezing point of the solution lowered to $-2.8^{\circ }\mathrm{C}$ ?
