What is the molality of 22.5 g acetone
(CH3)2CO , in 200 g water ?
( the answer is 22.0 m , that I think is wrong .. )
Answered by bobpursley
m= moles/kg solvent= (22.5/58)/.200

I get considerably less than 22.
Answered by MAD
but 22.5/58 = 0.3879 , and 0.3879/0.2 = 1.9
but the answer is another (22) .. I can't get it

The answer in the data base/text/whatever must be wrong. I get 1.93965 which I would round to 1.94 to 3 s.f.
