When converting from moles to grams you...

• Divide moles by molar mass (the atomic mass of compound)

• Multiple moles and molar mass (the atomic mass of compound)

• Divide moles by Liters

• Divide molar mass (the atomic mass of compound) by moles

When converting from grams to moles you...

• Divide grams by molar mass (the atomic mass of compound)

• Multiple grams and molar mass (the atomic mass of compound)

• Divide grams by Liters
