Discussion Overview

The discussion centers around calculating the number of hydrogen atoms in a 5g sample of pure hydrogen, exploring the relevant formulas and concepts involved in the calculation.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant initially asks about the number of hydrogen atoms in a 5g sample of hydrogen.
  • Another participant seeks clarification on what is meant by a "5 sample," leading to the correction that it refers to a 5g sample.
  • A participant suggests considering formulas that may assist in the calculation, specifically mentioning Avogadro's number.
  • Another participant provides a formula for calculating the number of atoms, indicating that it involves the number of moles and Avogadro's number, while also referencing the molecular weight of hydrogen.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the calculation, and the discussion remains unresolved regarding the specific numerical answer.

Contextual Notes

There are assumptions regarding the understanding of molecular weight and the application of Avogadro's number that are not fully explored in the discussion.

What is a "5 sample"?
 
sorry, a 5g sample.
 
Well, can you think of any formulae that can help you find this out? Does Avogadro's number ring a bell?
 
This looks like homework.
Number of atoms = Number of moles * Avogadro's Number
Use that with the molecular weight of Hydrogen for your answer.
