Question

4) If the outside temperature in winter is -9 °C, how many grams of ethylene glycol
(HO-CH,-CH,-OH) must be added in 1000 g of water so that this solution doesn't freeze in
outside temperature?

Expert Solution

Step 1

Freezing point of water = 0 ^◦C or 273.15 K

Freezing point of solution = - 9 ^◦C or (– 9 + 273.15) K

$\begin{array}{rcl} ∆ T_{f} & = & Freezing point of water - freezing point of solution \\ = & 273.15 K - (- 9 + 273.15) K \\ = & 273.15 K - 264.15 K \\ = & 9 K \end{array}$
