mole fraction = 0.0122
C
molality =0.684
Mass fraction =
260

Mole fraction =
((10/58.5)+(250/18))
(10/58.5)
=0.0122
Molality =

Answer:
Text Solution
Solution
Concentration of solution = Mass of soluteMass of solution×100
Mass of common salt = 35 g
Mass of water = 300 g
Mass of solution = (300 + 25) = 335 g
Concentration of solution = (35g)(335g)×100=10.45%
