A power plant burns $1.0 \times 10^{2}$ metric tons of coal that contains $3.0 \%$ (by mass) sulfur ( 1 metric ton $=10^{3} \mathrm{kg}$ ). The sulfur is converted to $\mathrm{SO}_{2}$ during combustion. a. How many metric tons of $\mathrm{SO}_{2}$ are produced? b. When $\mathrm{SO}_{2}$ escapes into the atmosphere it may combine with $\mathrm{O}_{2}$ and $\mathrm{H}_{2} \mathrm{O},$ forming sulfuric acid, $\mathrm{H}_{2} \mathrm{SO}_{4} .$ Write a balanced chemical equation describing this reaction. c. How many metric tons of sulfuric acid, a component of acid rain, could be produced from the quantity of $\mathrm{SO}_{2}$ calculated in part (a)?

Key Concepts

Percentage Composition

Percentage composition refers to the fraction of a compound's mass contributed by each element, expressed as a percentage. This concept is used to calculate the actual mass of a specific element within a given mass of a compound or mixture, which is fundamental in determining how much of that element is involved in chemical reactions.

Molar Mass Calculations

Molar mass is the mass of one mole of a substance, typically expressed in g/mol or kg/kmol. It serves as a conversion factor between the mass of a substance and the number of moles, a critical step in performing quantitative chemical calculations and relating masses of reactants to masses of products.

Stoichiometry

Stoichiometry involves the quantitative relationships between reactants and products as described by a balanced chemical equation. It is essential for calculating the amount of product formed from a given quantity of reactants, based on the mole ratios derived from the balanced equation.

Balanced Chemical Equations

Balanced chemical equations accurately represent a chemical reaction by ensuring the conservation of mass, meaning the number of atoms for each element is the same on both sides of the equation. This balance is crucial for correctly applying stoichiometric calculations in chemical reactions.

Mass-to-Mole and Mole-to-Mass Conversions

These conversion techniques are key for translating a given mass of a substance into moles, or vice versa, using the substance's molar mass. This process is essential for applying mole ratios from balanced chemical equations to predict the quantities of reactants and products in a reaction.
