Front

What is the definition of 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 a precipitate in a chemical reaction?

Back

A precipitate indicates that a chemical reaction has occurred, resulting in the formation of an insoluble solid.

Front

How do you calculate the molar mass of a compound?

Back

Add the atomic masses of all atoms in the molecular formula.

Front

What is the formula for calculating the number of moles?

Back

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