A certain liquid $x$ has a normal freezing point of $5\mathrm{.}60C$ and a freezing point depression constant $K_f=2\mathrm{.}27C*kg*mo{l}^{-1}*A$ solution is prepared by dissolving

some iron$($III$)$ chloride $(FeC{l}_3)$ in $850.$ g of $x.$ This solution freezes at $4\mathrm{.}0C.$ Calculate the mass of $FeC{l}_3$ that was dissolved.

Round your answer to $2$ significant digits.
