    Chemistry - Henry's Law/Raoult's Law

    Homework Statement At surface of the earth, 0.000488 moles of N2 dissolved in each liter of blood. (Ptot=1 atm at surface, and PN2 = 0.78 atm). Calculate Henry's law constant for N2(g) dissolving into blood at the Earth surface and then calculate the number of moles of N2(g) that would...

    How Do You Calculate ΔH and Determine Volume Changes in Thermodynamics?

    Hi All! I ran across a homework problem ans am confused by the question. here it is: For a certain process at constant pressure, ∆U = − 225 kJ and +52 kJ of expansion work is done. What is ∆H for this process and does the volume increase or decrease? I know that ∆U=q+w and therefore...
