[問題] 一題osmotic pressure and Ksp的題目 幫看答案對否.

[s27945 (22)]

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.
