Create a concept map **Chemical Quantities****Overview:**This section allows students to compare relationships between atoms, molecules, and moles and determine how to calculate their quantities.**Key Concepts:**- **Atomic mass**: A fundamental concept in chemistry used to quantify the mass of an individual atom.- **Atoms**: The basic units of chemical elements.- **Avogadro's number (6.022 x 10²³) of atoms/molecules**: A constant that provides the number of atoms or molecules in one mole of a substance.- **Grams to moles**: This conversion helps in determining the number of moles from a given mass.- **Molar mass**: The mass of one mole of a given substance, often expressed in grams per mole (g/mol).- **Mole(s)**: A unit of measurement for amount of substance, which contains Avogadro's number of entities.- **Moles to grams**: The calculation to convert moles back into a mass.- **Number of atoms/molecules to moles**: A conversion process to find the amount in moles from a specified number of atoms or molecules.**Diagram Explanation:**The diagram suggests relationships and functions related to chemical quantities, such as:- **Are counted using the**: Implies methods of quantification for atoms or molecules.- **Can be used to convert from**: Indicates conversion processes between different chemical quantities, like from grams to moles.- **Have**: Suggests ownership or characteristics of the entities involved, potentially referring to properties such as molar mass.- **Is used to calculate a molecule's**: Implies the use of these concepts and tools in molecular calculations.These elements work together to illustrate the interplay between atomic/molecular structures and their measurable quantities, essential for understanding chemical calculations.

If the mass of atom/molecule is given then the number of moles of the atom/molecule, n, is calculated as shown below. n=mass of atom/moleculemolar mass of the molecule/atom Using the calculated moles of atom/molecule, the number of atom/molecule, N, is calculated as shown below. Number of atom/molecule=NA×n=n mol×6.022×1023 atom/molecule per mol
