QUESTION:
Allicin is the compound responsible for the characteristic smell of garlic. An analysis of the compound gives the following percent composition by mass: C: 44.4 percent; H: 6.21 percent; S: 39.5 percent; 0: 9.86 percent. Calculate its empirical formula. What is its molecular formula given that its molar mass is about 162 g?
ANSWER:Step 1 of 3
Here, we are going to determine the molecular formula of the molecule Allicin.
Empirical formula represents the relative number of atoms of each element of the compound.
The molecular formula of a compound is obtained when the empirical formula is multiplied by a whole number.
Molecular formula = empirical formula x n
where n = 1, 2, 3,...
The valle of n can be calculated as follows:
For example: The empirical formula of Glucose is \(CH_2O\). Therefore the molecular formula of glucose will be = (\(CH_2O\)) n = \(C_nH_{2n}O_n\)
