Answer: norfenefrine
Explanation:
Depression in freezing point is given by:

= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant = 
m= molality

Weight of solvent (ethanol)= 
Molar mass of unknown non electrolyte = M g/mol
Mass of unknown non electrolyte added = 82 mg = 0.082 g (1g=1000mg)


The molecular mass of norfenefrine
is near to 154 and thus the identity of the white powder is norfenefrine .
