Chapter 10, Problem 55A

Interpretation Introduction

Interpretation: To determine the number of molecules in each compound

Concept Introduction: A group of two or more atoms that are chemically bonded together, whether they are from the same element or not, would be referred to as a molecule. For example, the water molecule is considered a combination of hydrogen and oxygen atom.

Answer to Problem 55A

Each molecule will have an identical number of atoms.

Explanation of Solution

One mole always contains the same number of molecules, which is known as Avogadro's number.

It can be said that the count of molecules in 1.00 mol of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ , 1.00 mol of ${\text{C}}_{\text{2}}{\text{H}}_{\text{6}}$ , or 1.00 mol of $\text{CO}$ would be identical. So, the number of molecules in each compound will be $\text{6}\text{.022}{\text{×10}}^{\text{23}}$ molecules.
