Discussion Overview
The discussion revolves around calculating the number of moles of nitrogen atoms in the compound C7H5(NO2)3 based on the number of oxygen atoms present in 12.6 grams of sugar. The scope includes homework-related calculations and mole conversions.
Discussion Character
- Homework-related, Mathematical reasoning, Debate/contested
Main Points Raised
- One participant calculates the moles of oxygen in sugar using a conversion factor, arriving at 0.42 moles of oxygen, and suggests dividing this by 3 to find the moles of nitrogen, but questions the correctness of this approach.
- Another participant proposes a different method, calculating the moles of sugar and then determining the number of oxygen atoms, ultimately suggesting a mass of 15.3 grams for the compound to equate the number of oxygen atoms.
- A participant questions the molar mass used for sugar, suggesting it should be 180 g/mole instead of 342 g/mole.
- Another participant raises the issue of which type of sugar is being referenced, listing various sugars to clarify the ambiguity.
- A later reply clarifies that glucose was intended, acknowledging the previous confusion.
- One participant suggests that 'sugar' can be assumed to be sucrose in the absence of specification.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the molar mass of sugar or the correct approach to the problem, indicating multiple competing views and unresolved calculations.
Contextual Notes
There are limitations regarding the assumptions made about the type of sugar and the molar mass used in calculations, which remain unresolved.
