A flask containing 450 $\mathrm{mL}$ of 0.500 $\mathrm{M}$ HBr was accidentally knocked to the floor. How many grams of $\mathrm{K}_{2} \mathrm{CO}_{3}$ would you need to put on the spill to neutralize the acid according to the following equation? $2 \mathrm{HBr}(a q)+\mathrm{K}_{2} \mathrm{CO}_{3}(a q) \longrightarrow 2 \mathrm{KBr}(a q)+\mathrm{CO}_{2}(g)+\mathrm{H}_{2} \mathrm{O}(l)$

Key Concepts

Molarity and Volume Relationship

This concept involves determining the number of moles of a solute present in a solution by using its molarity (moles per liter) and the given volume of the solution. Converting the volume from milliliters to liters and multiplying by the molarity yields the number of moles, which serves as the starting point for quantitative analysis in reactions.

Stoichiometry of Chemical Reactions

Stoichiometry refers to the quantitative relationships between reactants and products in a balanced chemical equation. It allows for the conversion of moles of one substance to moles of another using the mole ratios derived from the balanced chemical equation, which is essential for determining how much of a reactant is needed or how much product can be formed.

Neutralization Reactions

Neutralization reactions involve the reaction between an acid and a base to produce a salt and water, and sometimes additional products such as carbon dioxide when a carbonate is involved. Understanding this concept is critical in determining the amounts of acid and base required to completely neutralize each other based on their reaction stoichiometry.

Molar Mass and Mass-Mole Conversions

This concept involves converting between the mass of a substance and the number of moles by using its molar mass, which is the mass per mole of that substance. This conversion is key to determining how much of a substance (in grams) is required to provide a specific number of moles needed for a reaction.
