Silver nitrate and sodium phosphate are reacted in equal amounts of 200 g each. How many grams of silver phosphate are produced?
3AgNO₃+ Na₃(PO₄) ---> Ag₃(PO₄) + 3NaNO₃

CH₄ + 2O₂ → CO₂ + 2H₂O
24 grams of CH₄ was added to the above reaction. Calculate the theoretical yield of CO₂.

The ______________ yield is the maximum amount of product possible in a reaction. This determines the amount of product that should be produced in a perfect setting

When reacting Na with Cl₂, we calculated that the theoretical yield should be 12.5 grams. Our actual yield was 13.0 grams. What is the percent yield?

2Fe₂O₃ + C → Fe + 3CO₂
You add 28 grams of carbon. You find the actual yield to be 181.2 grams of CO₂. What is the percent yield of CO₂? (Hint: calculate theoretical yield of CO₂ first)
