A solution containing 34.2 g of cane-sugar `(C_(12)H_(22)O_(11))` dissolved in `500cm^(3)` of water froze at `-0.374^(@)C`. Calculate the freezing point depression constant of water.

Text Solution

AI Generated Solution

To solve the problem of calculating the freezing point depression constant (Kf) of water, we will follow these steps: ### Step 1: Identify the given data - Mass of cane sugar (C₁₂H₂₂O₁₁) = 34.2 g - Volume of water = 500 cm³ - Freezing point of the solution = -0.374 °C - Freezing point of pure water = 0 °C ...
