Consider the reaction: $$2 \mathrm{Ag}_{2} \mathrm{O}(s) \longrightarrow 4 \mathrm{Ag}(s)+\mathrm{O}_{2}(g)$$ If this reaction produces 15.8 $\mathrm{g}$ of $\mathrm{Ag}(s),$ what total volume of gas can be collected over water at a temperature of $25^{\circ} \mathrm{C}$ and a total pressure of 752 $\mathrm{mm} \mathrm{Hg}$ ?

Consider the reaction:
$$2 \mathrm{Ag}_{2} \mathrm{O}(s) \longrightarrow 4 \mathrm{Ag}(s)+\mathrm{O}_{2}(g)$$
If this reaction produces 15.8 $\mathrm{g}$ of $\mathrm{Ag}(s),$ what total volume of gas can be collected over water at a temperature of $25^{\circ} \mathrm{C}$ and a total pressure of
752 $\mathrm{mm} \mathrm{Hg}$ ?

Key Concepts

Stoichiometry

Stoichiometry involves using a balanced chemical equation to relate the quantities (in moles) of reactants and products. This concept allows you to convert between the mass of a substance and the number of moles, and then use the mole ratios provided by the balanced equation to determine the amount of a desired product or reactant.

Ideal Gas Law

The Ideal Gas Law (PV = nRT) relates the pressure, volume, number of moles, and temperature of a gas. It provides a framework for calculating any one of these variables when the others are known, and is fundamental in problems dealing with gas collection and measurements under different conditions.

Partial Pressures and Dalton's Law

When gases are collected over water, the total pressure includes contributions from both the gas of interest and water vapor. Dalton's Law states that the total pressure of a mixture of gases is the sum of the partial pressures of each individual gas, making it essential to subtract the water vapor pressure to find the pressure due solely to the gas produced in the reaction.

Conversion between Mass, Moles, and Volume

This concept covers the process of converting from a given mass of a substance to moles using its molar mass, and then to volume using gas laws. It integrates stoichiometric calculations with gas law application to arrive at a complete understanding of the reaction conditions and resultant gas volume.
