The active ingredient in aspirin is acetylsalicylic acid. in a lab class, a student uses paper chromatography to isolate another common ingredient of headache remedies. the sample of this ingredient had a mass of 384 mg and a volume of 0.32 cm3. looking at the following data, what was the other ingredient in the headache remedy? white table sugar caffeine sodium chloride d -0.70 g/ml d 1.2 g/ml d 2.2 g/ml

Caffeine

Explanation:

Density is defined as the ratio of mass of object to its volume. The mathematical expression of density is given as:

We are given:

Mass of ingredient= 384 mg =  (1g=1000mg)

Volume of ingredient=     (Conversion factor:  )

Putting values in above equation, we get:

Hence, the density of ingredient is 1.2 g/ml and it is caffeine.
