Problem on molar flow rate

I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267+5.234x10-3 T

a. What is the molar flow rate of the exit stream?
b. What sit eh temperature of the exit stream?

II. Consider the cooling of a glass of tap water by the addition of ice. The glass contains 400 ml of tap water at room temperature (250C) to which 100gm of ice is added. Assume the glass is adiabatic and that thermal equilibrium is obtained. The ice is originally at-100C when removed from the freezer and put in the glass for ice Hfus = -6.0 ( Kj/ mol)

a. What is the final temperature?
b. What % of the cooling  is achieved by leant heat ( the  melting of ice)?
