Molar Mass

Description:

Molar mass, also known as molecular mass or formula mass, is the mass of a substance given in atomic mass units (amu) divided by its amount in moles. It is a fundamental concept in chemistry and is used to calculate various properties of chemical substances.

Senses:

1. Chemistry: The mass of a given substance per mole.
2. Chemistry: The sum of the atomic masses of all atoms in a molecule.

Usage:

In chemistry, molar mass is an essential concept for calculating the amount of substance in moles using its mass or vice versa. It is also used in stoichiometry to determine the ratios of reactants and products in a chemical reaction.

Examples:

1. The molar mass of water (H₂O) is approximately 18.015 g/mol.
2. To determine the molar mass of carbon dioxide (CO₂), we add the atomic masses of carbon and two oxygen atoms.
