Question

In the following reaction, 451.4 g of lead reacts with excess oxygen forming 355.3 g of lead(II) oxide. Calculate the percent yield of the reaction.

Answer 1

so the formula to calculate percent yield is actual/predicted x100

Answer 2

the percent yield your trying to find for is lead (11) oxide since its a solid, precipitate

they are give you the actual yield of lead(II) oxide being 355.3 g

Answer 3

how to tell whether they give you actual is when the question might say, you collected, or through experimentation. Predicted is usually calculated through stoichiometry unless they give you the value of the predicted (they will say the predicted.....)



anyways you want the predicted value of lead (II) oxide. write out the balanced equation then use gravimetric stoich to obtain the number of grams of lead (II)oxide by using the 451.4 g of lead to start off.
