When
60.9
g
of urea
CH4N2O
are dissolved in
850.
g
of a certain mystery liquid
X
, the freezing point of the solution is
7.90°C
less than the freezing point of pure
X
.
Calculate the mass of iron(III) chloride that must be dissolved
in the same mass of
X
to produce the same depression in freezing point. The
van't Hoff factor
=i3.44
for iron(III) chloride in
X
.
Be sure your answer has a unit symbol, if necessary, and round
your answer to
3
significant digits.
