SUMMARY

The discussion centers on calculating the number of electrons in two small aluminum spheres, each weighing 0.0250 kilograms. The atomic mass of aluminum is 26.982 grams per mole, and its atomic number is 13, indicating that each atom has 13 electrons. The user initially calculated 7.25 x 1024 total electrons based on their moles of aluminum but received an incorrect answer. The correct approach requires ensuring the mass is converted accurately and considering the total number of atoms in both spheres.

PREREQUISITES
  • Understanding of atomic mass and moles
  • Knowledge of Avogadro's number (6.02 x 1023)
  • Familiarity with the concept of atomic number and electron configuration
  • Basic skills in unit conversion (kilograms to grams)
NEXT STEPS
  • Review calculations involving moles and atomic mass for aluminum
  • Learn about the relationship between mass, moles, and number of atoms
  • Study the concept of electron configuration in elements
  • Practice similar problems involving different elements and their electron counts
USEFUL FOR

Students in chemistry, physics enthusiasts, and educators looking to clarify atomic structure and electron calculations.

Two small aluminum spheres, each of mass 0.0250 kilograms, are separated by 80.0 centimeters.

How many electrons does each sphere contain? (The atomic mass of aluminum is 26.982 grams per mole, and its atomic number is 13.)

The attempt at a solution
I said that there are 6.02*10^23 atoms in a mole, and noted that after converting the mass into grams each sphere has .9265 moles. If the Aluminum spheres are uncharged there are 13 electrons per atom. I multiplied all three together to get 7.25*10^24 total electrons, but this comes up as the wrong answer.

Any guidance as to what I'm doing wrong will be highly appreciated, thanks
