Hello Raja
Here:
ΔTb=0.45K
w=0.4g weight of Anthracene.
W=25g weight of chloroform
Kb= Molal elevation constant(3.9K−Kg/mol)
m=Kb×w×1000W×ΔTb=3.9×0.4×25000×0.45 =17550kg/mol
I hope you understand my explanation and got cleared with the point. You can ask if you have any doubts in the comments section.
ALL THE BEST
