Dear Student,
As from the given data:
Figure moles of camphor 
Molar mass = 152 g/mol 
No. Of mole = 0.456/152 = x 
Mass of CH3)2CO = 31.4 g 
Molality = x*1000/31.4 =m 
Rise of BP = k*m 
K= 17.2 for each 100g 
= 1.72 Per Kg 
Cheers!!
Regards,
Vikas (B. Tech. 4th year

Rise = 1.72 * x*1000/31.4 
BP = 56.30+ rise.
