Question
Quinine is a natural product extracted from the bark of the cinchona tree, which is native to South America. Quinine is used as an antimalarial agent.When 1.83 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 4.71 Quinine is a natural product extracted from the bark of the cinchona tree, which is native to South America.

Explanation / Answer
The formula for freezing point depression is
?Tf = mkfi
kf is the freezing point constant
i is the Van't Hoff factor which in this case is 1
m is molality (moles of solute/kg of solvent)
?Tf is temperature change
?Tf is 2.17
