How many grams of carbon dioxide are produced if you react 200g of benzaldehyde reacr with 32g of oxygen?

its stoichiometry, i have no idea how to do this...

1. This is a limiting reagent problem. How do I know that? Because they give you BOTH amounts for the starting materials.
Here is how you do limiting reagent problems (they are just two stoichiometric problems rolled into one).

1. Write the equation and balance it.
2. Convert 32 g oxygen to moles. moles = grams/molar mass.
Convert 200 g benzaldehyde to moles the same way.
3a. Using the coefficients in the balanced eqution, convert moles benzaldehyde to moles CO2.
3b. Using the same procedure, convert moles oxygen to moles CO2.
3c. You will likely obtian two different values for the moles of CO2. Obviously, both can't be right. The correct value is the SMALLER (always the smaller) value and that material is the limiting reagent.
4. Using the value from 3c. convert moles to grams. g = moles x molar mass.
