Can you help me?
« on: June 22, 2013, 02:21:01 PM »
I've some thermodynamics problems.. Can somebody help me with them?

1) What's the molar fraction of oxygen dissolved in water at 1atm and 20°C, having the Henry constant at those conditions equal to 4.41 x 10^4 bar?

2) Determine the final temperature reached from 150g of ice at 0°C and 0.3dm^3 of water at 50°C ( delta Hfusion of water= 80cal/g; Cpwater=1 cal/ g°C)

Thank you so much, whoever will decide to answer :-)
