The normal freezing point of ethanol (CH3CH₂OH) is -117.30 °C and its Kip value is 1.99 °C/m. A nonvolatile, nonelectrolyte that dissolves in ethanol is saccharin. How many grams of saccharin, C₂H5NO3S (183.2 g/mol), must be dissolved in 245.0 grams of ethanol to reduce the freezing point by 0.400 °C? g saccharin.

TripAdvisor 33 of 40 I Review | Constants | Periodic Table Learning Goal: To become familiar with the concept and calculations of specific heat. Part A Specific heat (which can be represented as SH, Cs, sp. ht., or a number of other possibilities) is defined as the amount of energy needed to raise the temperature of 1 g of a substance by 1 °C. For example, 0.0920 cal is enough energy to raise 1 g of copper from 21.0 °C to 22.0 °C. Therefore, the specific heat of copper is 0.0920 cal/(g - °C). How much heat energy is required to raise the temperature of 0.360 kg of copper from 23.0 °C to 60.0 °C? The specific heat of copper is 0.0920 cal/(g- °C). Express your answer with the appropriate units. > View Available Hint(s) Using SH for specific heat, the formula for calculating specific heat is HA Value Units heat heat = SH = massxAT P…
