What is Molar Mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule.

How do you calculate the molar mass of a compound?

Back

To calculate the molar mass, add the atomic masses of all the elements in the compound, multiplied by the number of times each element appears in the formula.

Front

Which is heavier: 1 mole of bricks or 1 mole of cotton balls?

Back

1 mole of bricks is heavier than 1 mole of cotton balls because bricks have a greater mass per particle.

How does molar mass relate to the number of particles in a mole?

Back

One mole of any substance contains Avogadro's number of particles (approximately 6.022 x 10^23 particles), regardless of the substance's molar mass.
