Question
I need to find the empirical formula and the molecular formula using the following information
percent composition:
65.06% Carbon
8.53% Hydrogen
4.74% Nitrogem
21.67% Oxygen
Elyctrolyte no Number of ions/formula unit: _____
0.80 grams of the substance is disolved into 10.00 grams of cyclohexane. ____ grams of
substance is dissolved to make ______ ml of solution. The freezing point of the resulting
solution was determined to be 1.18 degrees C. From the above information determine the
empirical and molecular formula for the compound.
I came up with the empirical formula to be C16H25NO4. Is that correct?
I also need help filling in the blanks. This is all the information given and I am not very good
at chemistry and I need a little assistance to jog my memory.
Explanation / Answer
C16H25NO4 correct empirical and molecular formula
YES U R RIGHT :)
use formula of
depression in freezing point = Kf * molality
