When coal is burned, the sulfur present in coal is converted to sulfur dioxide $\left(\mathrm{SO}_{2}\right),$ which is responsible for the acid rain phenomenon. $$\mathrm{S}(s)+\mathrm{O}_{2}(g) \longrightarrow \mathrm{SO}_{2}(g)$$ If $2.54 \mathrm{kg}$ of $\mathrm{S}$ are reacted with oxygen, calculate the volume of $\mathrm{SO}_{2}$ gas (in $\mathrm{mL}$ ) formed at $30.5^{\circ} \mathrm{C}$ and 1.12 atm.

Key Concepts

Ideal Gas Law

The ideal gas law, expressed as PV = nRT, relates the pressure, volume, temperature, and number of moles of a gas. It provides a means to calculate any one of these variables when the other three are known, making it a vital tool for understanding the behavior of gases under various conditions.

Unit Conversion and Temperature Scale Adjustment

Accurate calculations in chemistry require consistent units across all measurements. This includes converting masses between units (such as kilograms to grams) and adjusting temperature values to the Kelvin scale, which is necessary for applying the ideal gas law and other thermodynamic equations.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between the reactants and products in a chemical reaction. It involves using a balanced chemical equation to determine how much of each substance is involved or produced in a reaction, ensuring that matter is conserved.

Mole Concept and Mass-to-Mole Conversion

The mole concept is a fundamental principle in chemistry that allows chemists to count particles by converting mass into moles using the substance's molar mass. This conversion is essential for relating macroscopic measurements to the number of molecules or atoms involved in a reaction.
