Discussion Overview

The discussion centers around the relationship between atomic mass units (amu) and molar mass, specifically how they can be considered equivalent under certain conditions. Participants explore the conceptual underpinnings of this equivalence and seek clarification on the topic.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the equivalence of amu and molar mass, suggesting that it seems impossible unless all atomic weights are the same.
  • Another participant asserts that amu is defined such that the molar mass in grams numerically equals the mass of the atom in amu.
  • A participant requests further explanation, indicating that the initial responses may not be sufficient for understanding.
  • One participant explains the relationship using an analogy involving pounds and kilograms, suggesting that the conversion factor (6.02x10^23 amu = 1g) is key to understanding the equivalence.
  • Another participant expresses confusion about the analogy, specifically regarding the term "gopher" used in the explanation.
  • A suggestion is made to check the meaning of "mole," indicating a potential gap in understanding fundamental concepts.
  • A participant acknowledges a previous comment, suggesting some level of agreement or shared understanding among participants.

Areas of Agreement / Disagreement

Participants express differing levels of understanding regarding the equivalence of amu and molar mass, with some seeking clarification while others provide explanations. There is no clear consensus on the topic, and the discussion remains unresolved.

Contextual Notes

Some participants appear to lack familiarity with key terms such as "mole," which may affect their understanding of the discussion. The analogy presented may also introduce confusion rather than clarity.

Who May Find This Useful

This discussion may be of interest to students or individuals seeking to understand the relationship between atomic mass and molar mass, particularly those who find existing explanations insufficient.

How amu is equal to Molar Mass ... Must S33

Hey fellows I want to know that how amu is equal to molar mass of element. I think it's not possible unless weight of atoms of all elements is same. And by doing so it will mean that as Carbon-12 has molar mass of 12g and 12 amu then (if weight of all atoms are equal) one gram of any substance will be equal to one amu. Please explain. ( I am really tired of Wikipedia's complicated explanation.)

amu is a unit selected in such a way that molar mass in grams equals (numerically) mass of the molecule (atom) expressed in amu. That's all.
 


I think it should need more explanation.
 


It all has to do with the fact that 6.02x1023 amu = 1g.

Here's a simpler analogy. A pound (Imperial weight unit) is equal to roughly 2 kg. Therefore, let's define a "gopher" as two of something. Now, let's say we have some rocks that each have a mass of 1kg. A "gopher" of rocks (two rocks) will have a mass of 2 kg or approximately one pound. Thus the mass of an individual rock in kg (1) is equal to the weight of one "gopher" of rocks in pounds (also 1).

Similarly, the mass of one atom in amu will be equal to the mass of a mole of that atom in grams simply because of the conversion between units above.
 


That helped until I found the meaning of of Gopher.
 


Check the meaning of mole.
 


Yeah . You was also post same! thanks.
