How many coulombs of positive charge are in 1.91 mol of O2 gas?

Click For Summary
SUMMARY

The discussion centers on calculating the total coulombs of positive charge in 1.91 moles of O2 gas. The correct approach involves using Avogadro's number (6.022 x 10^23) to determine the number of protons, resulting in 1.1502 x 10^24 protons. To convert protons to coulombs, the total number of protons is divided by the number of protons per coulomb (6.25 x 10^18), leading to the final calculation of charge. The participant initially made an error in this division but later resolved the issue independently.

PREREQUISITES
  • Understanding of Avogadro's number (6.022 x 10^23)
  • Basic knowledge of electric charge and coulombs
  • Familiarity with the concept of protons and their role in charge
  • Ability to perform unit conversions in chemistry
NEXT STEPS
  • Review the concept of Avogadro's number in chemical calculations
  • Learn about the relationship between charge, protons, and coulombs
  • Explore the principles of electrostatics and charge quantification
  • Practice additional problems involving moles and electric charge conversions
USEFUL FOR

Students studying chemistry, particularly those focusing on stoichiometry and electrochemistry, as well as educators looking for examples of charge calculations in gas reactions.

Homework Statement



How many coulombs of positive charge are in 1.91 mol of O2 gas?

Homework Equations



1 mol = 6.022x10^23 protons
q=Ne

The Attempt at a Solution



so 1.91 mols x 6.022x10^23 = 1.1502x10^24 protons

I divided that by 6.25x10^18 protons in one coulomb, but I got the wrong answer. Where am I going wrong?
