A shot of espresso has an average temperature after extraction of 90.1 °C. How many grams of ice at -14.7 °C are needed to cool the espresso to 0 °C. You can assume that the espresso will have a specific heat capacity and density equivalent to water. (Hint: AHfus-6.01 kJ/mol, Cice-2.09 J/g °C, 1 shot = 30.0 mL)
