El Hindenburg fue un dirigible lleno de hidrógeno, cuyo volumen era de $1.99 \times 10^8 \mathrm{~L}$. Si el hidrógeno usado fuera producido por la reacción de carbón con vapor de agua, ¿cuántos kilogramos de carbón se hubieran necesitado para producir el hidrógeno suficiente para llenar el dirigible a $20^{\circ} \mathrm{C}$ y $740 \mathrm{~mm}$ de presión? $$ \mathrm{C}(\mathrm{s})+\mathrm{H}_2 \mathrm{O}(\mathrm{g}) \longrightarrow \mathrm{CO}(\mathrm{g})+\mathrm{H}_2(\mathrm{~g}) $$

Key Concepts

Unit Conversion

Unit conversion is a key concept in chemistry that involves converting between different measurement units such as liters for volume, millimeters of mercury for pressure, degrees Celsius to Kelvin for temperature, and grams to kilograms for mass. Accurate conversions are critical to ensure that calculations using formulas like the ideal gas law are done correctly.

Molar Mass

The concept of molar mass is used to convert between the mass of a substance and the number of moles it represents. By knowing the molar mass of an element or compound, one can determine how much of it (in grams or kilograms) is required to have a specific number of moles, which is crucial in quantitative chemical calculations.

Ideal Gas Law

The ideal gas law (PV = nRT) is a fundamental equation in physical chemistry that relates the pressure, volume, and temperature of an ideal gas to the number of moles present. It is used to determine the number of moles of gas when the pressure, volume, and temperature are known, making it essential when calculating gas quantities under non-standard conditions.

Chemical Stoichiometry

Chemical stoichiometry involves using a balanced chemical equation to determine the quantitative relationships between reactants and products. It allows one to calculate how many moles or masses of a reactant are needed to produce a desired amount of product based on their mole ratios in the reaction.
