SUMMARY

The mass of a carbon atom is accurately expressed as 12 atomic mass units (amu) and 1.9924 x 10^-23 grams. This equivalence is derived from the fact that 6.023 x 10^23 atoms of carbon weigh 12 grams, leading to the calculation that one carbon atom weighs 12 amu. Additionally, the conversion to grams confirms that one carbon atom weighs 1.9924 x 10^-23 grams, validating both measurements as correct representations of carbon's atomic mass.

PREREQUISITES
  • Understanding of atomic mass units (amu)
  • Familiarity with Avogadro's number (6.023 x 10^23)
  • Basic knowledge of unit conversion between grams and amu
  • Concept of atomic structure and mass measurement
NEXT STEPS
  • Research the significance of Avogadro's number in chemistry
  • Learn about the concept of atomic mass and its applications
  • Explore the relationship between mass and moles in chemical calculations
  • Study unit conversion techniques in scientific measurements
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding atomic mass and its implications in chemical calculations.

12 amu and 1.9924 X 10^-23g express the mass of an atom of C?

Homework Equations

The Attempt at a Solution


Do 12 amu and 1.9924 X 10^-23g express the mass of an atom of C?
As I know,
6.023 X 10^23 atoms of C weighs 12 g,
1 atom of C weighs 1 X 12 / 6.023 X 10^23 = 12 amu -----------------------(1)
1 atom of C weighs.12 / 6.023 X 10^23 = 1.9924 X 10^-23 g ----------(2)
