6.41 g of a solute was added to 0.255 kg of water and ice, and colligative properties experiments determined that the freezing point decreased by 3.67°C. Using the Kf of water (1.86°C/m) and these data points, the molar mass of the solute was determined to be __________ . a. 3.23 g/mol b. 12.7 g/mol c. 25.5 g/mol d. The molar mass could not be determined.
