Explanation:

Given: Boiling point elevation =ΔTb = 1.76 K

Kb of acetic acid = 3.07 K kg mol-1

Mass of acetic acid = 50 g

To find: Molality of the solution

Formula: ΔTb = Kb m

Calculation: Using formula and rearranging, we get,

m

Tb

Kb

K

K kg mol

mol kgm=△TbKb=1.76K3.07K kg mol-1=0.573 mol kg-1 = 0.573 m

The molality of the solution is 0.573 m.
