Find molality of solution
Asked by | 20 Jul, 2008, 01:20: PM
Expert Answer
Molality= no of moles/weight of solvent in kg
No of moles of solute= 8.653/58.5
=147.91
weight of solvent= wt of solution –wt of solute
wt of solution = density x volume
= (1.0816/1000) x 100
=108.16x10-3g
wt of solvent = (108.16x10-3)- 8.653=-8.544g
molality= 147.91 X 1000/-8.544
=17.31x103
