Front

What is Avogadro's number?

Back

6.022 x 10²³, the number of particles in one mole of a substance.

Front

Define molar mass.

Back

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is the significance of balancing chemical equations?

Back

It ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What is the formula to calculate the number of moles?

Back

Number of moles = mass (g) / molar mass (g/mol).
