There is good and bad bacteria that can be both harmful and good for humans
Solution :
We know that :
and 
Then,
..................(1)
Where,
= amount of solvent (in kg)
= amount of solute (in kg)
= molar mass of solute (g/mole)
= molality of solution (mole/kg)
Given :
=
, 


= 0.250 kg,
= 24.3 g
Then putting this values in the equation is (1),


g/mole
So, the molar mass of the unknown compound is 158.49 g/mole.
