The normal freezing point of ethanol (CH3CH2OH) is -117.30 °C and its Kfp value is 1.99 °C/m. A nonvolatile, nonelectrolyte that dissolves in ethanol is testosterone . How many grams of testosterone, C19H28O2 (288.4 g/mol), must be dissolved in 288.0 grams of ethanol to reduce the freezing point by 0.500 °C?
