SUMMARY

The discussion clarifies the relationship between atomic mass units (amu) and molar mass, emphasizing that 1 mole of any substance contains approximately 6.02 x 1023 atoms, which corresponds to 1 gram. Specifically, the molar mass of an element in grams is numerically equal to its atomic mass in amu. For example, Carbon-12 has a molar mass of 12 grams and an atomic mass of 12 amu. This equivalence is a fundamental concept in chemistry that simplifies the understanding of mass relationships in chemical reactions.

PREREQUISITES
  • Understanding of atomic mass units (amu)
  • Familiarity with the concept of a mole in chemistry
  • Basic knowledge of unit conversions in scientific measurements
  • Awareness of Avogadro's number (6.02 x 1023)
NEXT STEPS
  • Study the concept of Avogadro's number and its significance in chemistry
  • Learn about the periodic table and how molar mass is determined for different elements
  • Explore the relationship between mass and moles in chemical reactions
  • Investigate the implications of atomic mass on stoichiometry in chemical equations
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding the fundamental principles of atomic mass and molar mass relationships in chemical science.

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.
