Problem: Calculate the empirical formula for each of the following stimulants based on their elemental mass percent composition.nicotine (found in tobacco leaves): C 74.03%, H 8.70%, N 17.27%

FREE Expert Solution

We have to calculate the empirical formula of nicotine using the given percentages of elements.


The given percentages are: C 74.03%, H 8.70%, N 17.27%


Empirical formula is a chemical formula that gives the relative proportions of elements in a compound but not the actual number of atoms of elements in a compound.


Empirical formula of a compound can be calculated using these steps:

Step 1: Find the masses of elements in the compound.

Step 2: Find the percentages elements in the compound.

Step 3: Dividing the percentages of elements by their average atomic masses.

Step 4: Dividing the obtained numbers by the smallest number among them and rounding off to the nearest whole numbers to get the empirical formula.
