:5. [10 points) The final stage in refining the metal lead (Pb) is to react lead(II) oxide with carbon, producing lead and carbon dioxide. If 225 g Pbo reacts with 10.0 g C: a. Write the balanced equation for this reaction. b. What is the limiting reactant? c. What is the theoretical yield?
The Scrum Guide suggests that "refinement usually consumes no more than 10% of the capacity of the Development Team."
Can you explain if this is for one meeting or total refinement meeting in a Sprint ?
Simple, do you think the capacity is for entire sprint or only on the day you plan refinement? So it is for the team capacity of the entire Sprint. This will answer your next question
Say if we have 6 DEV in 3 week sprint , and we want to have only 2 refinement sessions , how much time we can spend ?

It does not matter whether you have 2, 3 or one sessions (I would suggest a more consistent and regular approach of once a week that will address the responding to change from Scrum Guide. All you have to try is to not to cross 10% of the capacity. Note: even this is not mandatory the word usually means its an observation and best practice and not mandatory ! you may have a complex product and may need more than 10% to refine. The work usually lets to cross this time. So do not try to play it to the book especially when the book uses the words usually for obvious reasons.
For a 40 hr week if you want to stay close to the suggestion you need to spend less than 10% of 40 hrs = 4 hrs of refinement sessions per week. Therefore it does even matter how long your sprint is! It's a simple understanding of not to cross 4 hrs (10%) of a weeks 40hrs time per individual (all of them together spend 4X6 = 24 man hours of course !)
In short ...
Just try to keep your refinement sessions under 4 hrs a week
....unless your product's complexity needs more time especially at the beginning or during technical spikes (-->NOT a scrum term!)
