1.9—Percentage yields and percentage atom economies (by mass) in laboratory and industrial processes

Be able to calculate percentage yields and percentage atom economies (by mass) in laboratory and industrial processes, using chemical equations and experimental results Atom economy = molar mass of the desired product × 100% sum of the molar masses of all products.

Use —percentage yields and percentage atom economies (by mass) in laboratory and industrial processes to connect the rule to the data and decision in the question.

This matters because —percentage yields and percentage atom economies (by mass) in laboratory and industrial processes determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —percentage yields and percentage atom economies (by mass) in laboratory and industrial processes to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Percentage yields and percentage atom economies (by mass) in laboratory and industrial processes is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
