Flashcard: Molar mass and mole conversions

Front

What is the molar mass of CO₂?

Back

The molar mass of CO₂ (carbon dioxide) is approximately 44.01 g/mol.

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: Moles = Mass (g) / Molar Mass (g/mol).

Front

What is Avogadro's number?

Back

Avogadro's number is 6.02 x 10²³, which is the number of particles (atoms, molecules) in one mole.

Front

How many moles are in 454 grams of CO₂?

Back

10.3 moles (calculated using the molar mass of CO₂).

Front

What is the conversion factor for moles to molecules?

Back

1 mole = 6.02 x 10²³ molecules.

Front

How do you calculate the number of moles in a given mass of NaCl?

Back

Use the formula: Moles = Mass (g) / Molar Mass (g/mol). The molar mass of NaCl is approximately 58.44 g/mol.

Front

How many moles are in 200 grams of NaCl?

Back

3.42 moles (calculated using the molar mass of NaCl).

Front

What is dimensional analysis?

Back

Dimensional analysis is a method used to convert between units using conversion factors.

Front

How do you convert grams of an element to atoms?

Back

Use the formula: Atoms = (Mass (g) / Molar Mass (g/mol)) x Avogadro's number.
