. For quick preparation of a cup of hot chocolate in a cafeteria, cocoa powder and sugar
are added in a cup of water and the solution is heated by direct steam injection. If the
initial temperature of all the ingredients is 15 ℃, the final temperature is 95℃, the mass
of the solution is 150g initially, and the heat capacity of the solution is 3.8 kJ/kg ℃,
calculate how much saturated steam at 110 ℃ will be used. State your assumptions.
