Introduction
Molar mass is a fundamental concept in chemistry, representing the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The unit of molar mass is grams per mole (g/mol). It helps us in converting between the mass of a substance and the number of moles, which is crucial for stoichiometric calculations.
A mole is a unit that measures the amount of substance. One mole contains exactly Avogadro’s number of particles, which is approximately 6.022 x 1023 particles. The mass of one mole of a substance is equal to its molar mass. This relationship is fundamental in chemistry, aiding conversions between different units.
The key equations involving molar mass, moles, and mass are:
Moles = Mass / Molar Mass
This equation allows you to determine the number of moles present in a given mass of a substance.
Mass = Moles * Molar Mass
Using this equation, you can calculate the mass of a substance if you know the number of moles and its molar mass.
To simplify these calculations, you can use our free molar mass calculator, which can quickly and accurately compute results for you.
How to Calculate Molar Mass
To calculate moles from molar mass, first, you need the mass of the substance. Then, use the equation:
Moles = Mass / Molar Mass
For example, if you have 10 grams of a substance with a molar mass of 5 g/mol, you can calculate the moles as follows:
Moles = 10 g / 5 g/mol = 2 moles
