Converting Liters of Oxygen to Moles

The video tutorial explains how to convert one liter of oxygen gas to moles using two methods: the mole map and conversion factors. Both methods yield the same result of 0.045 moles. Additionally, it covers how to convert moles to grams by multiplying by the molar mass of O2.

What are the two methods mentioned for converting liters of oxygen gas to moles?

• Mole map and conversion factors

• Mole map and chemical equations

• Mole map and stoichiometry

• Conversion factors and chemical equations

In the mole map method, what is the conversion factor used to convert liters to moles?

• 24.0 liters per mole

• 22.4 liters per mole

• 20.0 liters per mole

• 18.0 liters per mole

What is the result of dividing 1 liter by 22.4 in the mole map method?

• 0.055 moles

• 0.040 moles

• 0.050 moles

• 0.045 moles

When using conversion factors, why do we place liters on the bottom of the fraction?

• To convert liters to grams

• To add liters

• To ensure liters are multiplied

• To cancel out liters

What is the final result when using conversion factors to convert 1 liter of oxygen gas to moles?

• 0.055 moles

• 0.040 moles

• 0.050 moles

• 0.045 moles

What is the next step if you want to convert moles of oxygen gas to grams?

• Add the molar mass of O2

• Divide by the molar mass of O2

• Subtract the molar mass of O2

• Multiply by the molar mass of O2
