The questions get harder as you go, so try your best.
Read this short article for more information on theoretical and percent yield: https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Introductory_Chemistry_(CK-12)/12%3A_Stoichiometry/12.09%3A_Theoretical_Yield_and_Percent_Yield
Be careful with what the question is asking (moles vs. grams)!
To find the answers: highlight the section following "Answers" (text is in white: if you highlight it, you should be able to see it)!
