SUMMARY

1.0 mol of O2 gas contains a total of 1.54 x 10^5 Coulombs of positive charge in its atomic nuclei. This calculation is derived using the formula Q = ne, where n is the number of protons and e is the charge of a proton. Each O2 molecule consists of two oxygen atoms, each contributing 8 protons, leading to a total of 16 protons per molecule. Utilizing Avogadro's number (6.02 x 10^23), the total charge is calculated as 1.0 mol O2 x 6.02 x 10^23 molecules/mol x 16 protons/molecule x 1.60 x 10^-19 Coulombs/proton.

PREREQUISITES
  • Understanding of basic chemistry concepts, specifically molecular composition.
  • Familiarity with the concept of charge and the elementary charge of a proton (1.60 x 10^-19 Coulombs).
  • Knowledge of Avogadro's number (6.02 x 10^23) and its significance in mole calculations.
  • Ability to perform calculations involving multiplication and scientific notation.
NEXT STEPS
  • Study the concept of moles and Avogadro's number in greater detail.
  • Learn about the structure of molecules and how to determine the number of protons in different elements.
  • Explore the relationship between charge, protons, and electrons in atomic theory.
  • Investigate other calculations involving Coulombs and charge in different chemical contexts.
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding the charge distribution in molecular gases, particularly in relation to O2 gas and its atomic structure.

Homework Statement


Suppose you have 1.0 mol of O2 gas. How many Coulombs of positive charge are in the atomic nuclei of this gas?


Homework Equations


I assume you would use Q=ne with Avogadro's number...


The Attempt at a Solution


1 mol O2/ 6.23 x 10^23 * 8 protons * 1.60 x 10^-19

There are two oxygen atoms in every molecule of O2... I cannot tell if you took that into account? You got the charge in Coulombs of 1 proton. And you did write down how many O2 molecules are contained in 1 mole of O2... And you did type the number of protons (atomic number) in one oxygen atom...8

Maybe that's just a typo. If not, you should look up the value of Avogadro's number.
