Nomenclature, molecular mass, moles help (attempted problems already)

Click For Summary

Discussion Overview

The discussion revolves around the concepts of nomenclature, molecular mass, and moles, particularly focusing on the participant's attempts to solve related problems. The scope includes theoretical understanding and practical application of these concepts in chemistry.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant shares their attempts at solving problems related to molecular mass and moles, specifically asking for feedback on their correctness.
  • Another participant poses a question about the grams of water in one mole, hinting at the need to review the definition of a mole.
  • A subsequent response suggests a calculation method for determining the mass of water in one mole, involving the atomic masses of hydrogen and oxygen.
  • Another participant expresses concern that the original poster does not fully grasp the concept of a mole.

Areas of Agreement / Disagreement

The discussion shows a lack of consensus, with some participants questioning the understanding of the mole concept while others focus on specific calculations. Multiple viewpoints on the correct approach to the problems remain unresolved.

Contextual Notes

There are indications of missing foundational understanding regarding the mole concept, and the calculations presented may depend on the correct interpretation of molecular mass and nomenclature.

Who May Find This Useful

This discussion may be useful for students seeking clarification on the concepts of moles, molecular mass, and nomenclature in chemistry, particularly those working on related homework problems.

Alright, below are screen captures of some work that I'm tackling. They show my attempts and answers at the problems. I would like to know whether I'm correct or wrong and how to correct the mistakes. The one I need most help with is, the one where you're given density and asked to find molecules. Help will be greatly appreciated. Thanks in advance.

would I have to calculate it as so:

H: 2x(1.008)
O: 1x(16.00)
--------------
H2O:18.016 mol H20 ? and use that instead in the conversion factor?

What about my other problems. Are they okay?
 
You still are not understanding the concept of what a mole of a substance is.
