SUMMARY

The total number of electrons in 1 kg of water (H2O) can be calculated by first determining the number of molecules in that mass using Avogadro's number. Each water molecule contains 10 electrons (2 from hydrogen and 8 from oxygen). Therefore, to find the total electron count, multiply the number of molecules in 1 kg of water by 10. This method provides a definitive approach to calculating electron quantity in a given mass of water.

PREREQUISITES
  • Understanding of Avogadro's number (6.022 x 10^23 molecules/mol)
  • Basic knowledge of molecular composition of water (H2O)
  • Familiarity with the concept of moles in chemistry
  • Knowledge of electron charge (-1.6 x 10^-19 C)
NEXT STEPS
  • Calculate the number of molecules in 1 kg of water using the mole concept
  • Learn about molecular structure and electron configuration of H2O
  • Explore the relationship between mass, moles, and molecular count
  • Investigate the significance of electron charge in chemical reactions
USEFUL FOR

Students in chemistry, educators teaching molecular concepts, and anyone interested in the quantitative analysis of substances in chemical reactions.

what is the total electron change in 1 kg of H2O?


well I know I can solve this one by myself but that would take me some hours to figure out what to do so it's probably less cluttering and memorizing wrong things if I post it here

I know an electron has a charge of -1.6x10^-19C
I know an H2O molecule is neutral, so has the same number of electrons and protons

what I don't know is how to figure out how many electrons there are in 1kg of H2O, or if I even need to know that.

anyone?
 
Find the number of electrons in one molecule of water. Then calculate the number of molecules in one kilogram of water using Avogadro number and mole concept.
