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 significance of molar mass in chemical reactions?

Back

Molar mass is crucial for converting between grams and moles, allowing chemists to calculate reactants and products in chemical reactions.

Front

What is the relationship between moles and molar mass?

Back

The number of moles of a substance can be calculated by dividing the mass of the substance (in grams) by its molar mass (g/mol).

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance by its molar mass.
