Chapter 15, Problem 97AP

Interpretation Introduction

Interpretation:

The volume of ${\text{NH}}_{\text{3}}$ at $\text{STP}$ required to prepare $100.\text{mL}$ of concentrated ammonia solution is to be calculated.

Concept Introduction:

Solution is composed of solute and solvent particles. Solute particles are always present in lower amount as compared to amount of the solvent in the solution. The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element.

The molarity is calculated by the formula,

$\text{Molarity}=\frac{\text{Number}\text{of}\text{moles}\text{of}\text{solute}}{\text{Volume}\text{of}\text{solution}\left(\text{L}\right)}$.
