Theoretical Yield/Percent Yield

Where did the 4 in front of 4 mol KO₂ come from?

• The periodic table

• The coefficient in front of KO₂ in the balanced equation

• The molar mass

• The coefficient in front of KOH in the balanced equation

Which numbers are going to go in front of Mol O₂ and mol H₂O in the calculation?

Put the following conversion steps in order:

1. 1.Use the molar mass to convert from moles CO₂ to grams of CO₂

2. 2. Use the mole to mole ratio to convert from moles C₂H₂ to moles CO₂

3. 3. Use the molar mass to convert from g C₂H₂ to mol C₂H₂

• 3, 2, 1

• 1, 2, 3

• 2, 3, 1

• none of the above
