A solution of ammonia and water contains 3.50×1025 water molecules and 9.00×1024 ammonia molecules. How many total hydrogen atoms are in this solution?
Any help would be appreciated, thank you!
Hydrogen atoms=2*watermolecules+ 3*ammoniamolecules
Water: H2O
ammonia NH3
To determine the total number of hydrogen atoms in the solution, we need to consider both the ammonia and water molecules separately.
First, let's calculate the number of hydrogen atoms in 9.00×10^24 ammonia molecules. Each ammonia molecule (NH3) contains 3 hydrogen atoms. So, we multiply the number of ammonia molecules by 3 to find the total number of hydrogen atoms in the ammonia solution:
9.00×10^24 ammonia molecules x 3 hydrogen atoms/molecule = 2.70×10^25 hydrogen atoms
Next, let's calculate the number of hydrogen atoms in 3.50×10^25 water molecules. Each water molecule (H2O) contains 2 hydrogen atoms. So, we multiply the number of water molecules by 2 to find the total number of hydrogen atoms in the water solution:
3.50×10^25 water molecules x 2 hydrogen atoms/molecule = 7.00×10^25 hydrogen atoms
Finally, to find the total number of hydrogen atoms in the solution, we add the number of hydrogen atoms from ammonia and water:
2.70×10^25 hydrogen atoms (from ammonia) + 7.00×10^25 hydrogen atoms (from water) = 9.70×10^25 hydrogen atoms
Therefore, the solution contains a total of 9.70×10^25 hydrogen atoms.
