标题[问题] Colligative properties
时间Wed Dec 29 01:31:59 2010
题目：Estimate the depression of freezing point of the most concentrated of
these solutions, taking Kf as about 10 K/(mol kg^-1).
这一题是Atkins的物化课本p.156 self-test 5.6
上面那一题的Example给的资料我不知道怎麽求出解答
答案是0.8mK
these solutions →The osmotic pressures of solutions of poly(vinyl chloride),
PVC, in cyclohexanone at 298K are given below. The pressures
are expressed in terms of the heights of solution
(of mass density ρ = 0.980 g cm^-3)in balance with the
osmotic pressure.
c/(g dm^-3) 1.00 2.00 4.00 7.00 9.00
h/cm 0.28 0.71 2.01 5.10 8.00
能否请版上的各位高手们帮忙解答 感谢~~~:)
