3. Calculate the final temperature (once the ice has melted) of a mixture made up initially of 70.0mL liquid water at 28.0C and 5.0g ice at 0.0C. 4. How many grams of steam at 100C would be required to raise the temperature of 47.6g solid benzene (C6H6) from 5.5C to 30.0C ? Assume that heat is only transferred from the steam (and not liquid water) and that the steam/water and benzene are separated by a glass wall and do not mix. (The melting point of benzene is 5.5C;Hfu for benzene is 9.87kJ/mol; specific heat for benzene is 1.63 J/gC;Hvp for steam at 100C is 40.7kJ/mol.)
