Answer : The molar mass of unknown compound is 152.38 g/mole
Explanation :
Depression in freezing point = 
Mass of unknown compound = 16.5 g
Mass of water = 106.0 g
Formula used :
where,
= depression in freezing point
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water = 
m = molality
Now put all the given values in this formula, we get
Therefore, the molar mass of unknown compound is 152.38 g/mole
