(Solved): A certain lyquid \( X \) has a normal boiling point of \( 134.40=\mathrm{C} \) and a boiling point ...




A certain lyquid \( X \) has a normal boiling point of \( 134.40=\mathrm{C} \) and a boiling point clevation constant \( K .0
A certain lyquid \( X \) has a normal boiling point of \( 134.40=\mathrm{C} \) and a boiling point clevation constant \( K .0 .67 \) " \( \mathrm{C} \cdot \mathrm{kg} \) mol \( { }^{-1} \). A solubin is nrepared by dissolving. some alanine \( \left(\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{NO}_{2}\right) \) in \( \left.30^{\circ}\right)_{\text {. g of }} \mathrm{X} \), This solution boils at \( 135.6 . \mathrm{C} \), Calculate the mass of \( \mathrm{C}_{1} \mathrm{H}_{7} \mathrm{NO}_{2} \) that was dissolved. Be sure your answer is rounded to the correct number of significiant digits.
