If a cube of table sugar, which is made of sucrose, $\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11},$ is added to concentrated sulfuric acid, the acid "dehydrates" the sugar: it removes the hydrogen and oxygen from it, leaving behind a lump of carbon. What percentage of the initial mass of sugar is carbon?

Key Concepts

Stoichiometry

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It involves using balanced chemical equations and molar mass relationships to predict the amounts of substances consumed and produced, ensuring that the law of conservation of mass is maintained.

Molecular Formula and Molar Mass Calculation

This concept involves determining the total mass of a compound by summing the atomic masses of all atoms specified in its molecular formula. It forms the basis for quantitative analysis in chemistry by allowing one to relate the masses of constituent elements to the whole compound.

Percentage Composition

Percentage composition refers to the method of calculating the relative mass percentage of each element within a compound. By dividing the mass of each individual element (as determined from the formula and atomic masses) by the total molar mass of the compound and multiplying by 100, one can understand the proportion of the compound's mass contributed by that element.
