Molar Mass and Molar Conversions Flashcard

Front

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, identify the number of each type of atom in the compound, multiply by the atomic mass of each element, and sum the total.

What is the molar mass of Calcium Nitrate, Ca(NO3)2?

Back

164.09 g/mol.

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance (in grams) by its molar mass (in g/mol). Formula: Moles = Mass (g) / Molar Mass (g/mol).

What is the molar mass of Sodium Chloride, NaCl?

Back

58.44 g/mol.

Front

How do you convert moles to grams?

Back

To convert moles to grams, multiply the number of moles by the molar mass of the substance. Formula: Mass (g) = Moles × Molar Mass (g/mol).
