Study Notes

Molar mass is the mass of one mole of a substance
It is a measure of the total mass of a substance that contains as many particles as there are atoms in 0.012 kilograms of carbon-12

Molar mass can be calculated by summing the atomic masses of all the atoms in a molecule
Formula: Molar mass = (sum of atomic masses of all atoms) / (number of atoms in the molecule)
Example: Calculate the molar mass of CO2
- Atomic mass of C = 12.01 g/mol
- Atomic mass of O = 16.00 g/mol (x2)
- Molar mass of CO2 = (12.01 + 16.00 + 16.00) g/mol = 44.01 g/mol

Molar mass is used to convert between the amount of a substance (moles) and its mass (grams)
Essential in stoichiometry, the study of the quantitative relationships between reactants and products in chemical reactions
Used in fields such as chemistry, physics, and biology to calculate the masses of substances and particles

Molar mass is the mass of one mole of a substance, defined as containing as many particles as there are atoms in 0.012 kilograms of carbon-12.

Molar mass is calculated by summing the atomic masses of all atoms in a molecule.
The formula for calculating molar mass is: Molar mass = (sum of atomic masses of all atoms) / (number of atoms in the molecule).
For example, the molar mass of CO2 is calculated as: (12.01 g/mol + 16.00 g/mol + 16.00 g/mol) = 44.01 g/mol.

Molar mass is typically expressed in units of grams per mole (g/mol).
It can also be expressed in kilograms per mole (kg/mol), although this is less common.
