Chapter 4, Problem 94AP

Interpretation Introduction

Interpretation:

The molarity of $\text{HCl}$ solution is to be determined that can react with given mass of pure form of sodium carbonate $\left({\text{Na}}_2{\text{CO}}_3\right)$.

Concept introduction:

Limiting reagent in a reaction is the substance thatis completelyconsumed when the reaction gets completed.

The amount of product formed is determined by the amount of limiting reagent present in the reaction. This is because when the limiting reagent gets consumed, the reaction stops.

The number of moles of a reactant is calculated by the following formula:

$m=\frac{wt}{Mw}$

Here, $m$ is the number of moles of the compound, $wt$ is the weight of the compound, and $Mw$ is the molecular weight of the compound.

The concentration of a solution in terms of molarity is determined by the following formula:

$M=\left(m\right)\left(\frac{1}{V}\right)$

Here, $M$ is the concentration of the compound in molarity, $m$ is the number of moles of the compound, and $V$ is the volume of the solution containing the compound.
