2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is percentage yield?
Show answer
$percentage yield=actual yieldtheoretical yield×100\text{percentage yield} = \frac{\text{actual yield}}{\text{theoretical yield}} \times 100$
What is atom economy?
Show answer
$atom economy=molar mass of desired producttotal molar mass of all products×100\text{atom economy} = \frac{\text{molar mass of desired product}}{\text{total molar mass of all products}} \times 100$
