Cytosine, a constituent of deoxyribonucleic acid (DNA) can be represented by the following molecular model. If 0.001 mol of cytosine is submitted to combustion analysis, how many moles of $\mathrm{CO}_{2}$ and how many moles of $\mathrm{H}_{2} \mathrm{O}$ would be formed? (Gray $=\mathrm{C},$ red $=\mathrm{O},$ blue $=\mathrm{N},$ ivory $=\mathrm{H.}$ )

Key Concepts

Combustion Analysis

Combustion analysis is a technique used to determine the elemental composition of a compound by burning it in oxygen. In this process, all the carbon in an organic compound converts to carbon dioxide (CO2) and all the hydrogen converts to water (H2O). This method allows one to deduce the amounts of carbon and hydrogen present in the original sample based on the quantities of CO2 and H2O produced.

Mole Concept

The mole concept is essential in chemistry as it offers a way to relate the number of particles in a substance to its mass, using Avogadro's number. This concept allows chemists to convert between the given moles of a substance and the number of molecules or atoms, facilitating quantitative comparisons in chemical reactions.

Stoichiometry

Stoichiometry involves using the relationships set by a balanced chemical equation to determine the amounts of reactants and products involved in a chemical reaction. It is the process of converting moles of one substance to moles of another through established mole ratios, ensuring that mass and atoms are conserved in the reaction.

Balancing Chemical Equations

Balancing chemical equations is the process of ensuring that the number of atoms for each element is equal on both the reactant and product sides of a chemical reaction. This reflects the law of conservation of mass and provides the necessary coefficients that form the foundation for accurate stoichiometric calculations.
