標題[問題] 一題osmotic pressure and Ksp的題目 幫看答案對否.
時間Wed Jul 7 07:18:03 2010
6. The osmotic pressure of a solution saturated with a salt M3X2 is 2.64 x 10(-
2次方) atm at 25度C.
Calculate Ksp value for M3X2, assuming ideal behavior. (R = 0.08206 L atm/ K
mol)
算法:
0.0264 = 5s x 0.08206 x 298
s = 0.0264 / (5 x 0.08206 x 298)
Ksp = 108s(5次方)
Ksp = 5.068 x 10(-17次方)
這樣算答案對嗎?請大家幫忙看一下算法有無錯誤.
