ok so i have a double displacement reaction the reactants are in ml they are aqueous solutions, anyway i need to find the precent yeild, i already have the actual yeild but how do i find the predicted yield?

i would love to help, problem is... im only in 10th grade.... hm but now that im re reading it..
and this is just a guess...
since its PREDICTEDyield i think they want you to predict waht the yield is (not sure what the yeild is but, i bet you know =]) before u knew the actual yeild hoped i helped :P

You get the predicted yield by seeing how many moles you had of the limiting reagent, how many moles of product that should ideally give rise to, and then multiplying that last number by the molar mass of the product.
If you took your reagents in the correct ratio for reaction, either one can be considered "limiting" in this calculation.
