A solution of ammonia and water contains 3.50×10^25 water molecules and 5.00×10^24 ammonia molecules. How many total hydrogen atoms are in this solution?
Molecular formula for water: H2O
Molecular formula for ammonia: NH3
1 H2O molecule has 2 H atoms
1 NH3 molecule has 3 H atoms
3.50 * 10^25 H2O molecules * 2 H atoms/H20 molecule = 7 * 10^25 H atoms for the water part of the solution
5.00 * 10^24 NH3 molecules * 3 H atoms/NH3 molecule = 1.5*10^25 H atoms for the ammonia part of the solution
7 * 10^25 H atoms from water + 1.5 * 10^25 H atoms from ammonia = 8.5 * 10^25 total H atoms
(it's a bit late so my math might be slightly off, but that's the gist of it. I think you can handle plugging in the numbers)

To find the total number of hydrogen atoms in the solution, we need to calculate the number of hydrogen atoms in water and ammonia separately.
1. Water (H2O):
Each water molecule contains 2 hydrogen atoms.
The solution has 3.50×10^25 water molecules, so the total number of hydrogen atoms from water is:
2 hydrogen atoms/molecule * 3.50×10^25 water molecules = 7.00×10^25 hydrogen atoms from water.
2. Ammonia (NH3):
Each ammonia molecule contains 3 hydrogen atoms.
The solution has 5.00×10^24 ammonia molecules, so the total number of hydrogen atoms from ammonia is:
3 hydrogen atoms/molecule * 5.00×10^24 ammonia molecules = 1.50×10^25 hydrogen atoms from ammonia.
Now, we can calculate the total number of hydrogen atoms in the solution by adding the contributions from water and ammonia:
Total hydrogen atoms = Hydrogen atoms from water + Hydrogen atoms from ammonia
Total hydrogen atoms = 7.00×10^25 hydrogen atoms from water + 1.50×10^25 hydrogen atoms from ammonia
Total hydrogen atoms = 8.50×10^25 hydrogen atoms
Therefore, there are 8.50×10^25 hydrogen atoms in this solution.
To find the total number of hydrogen atoms in the solution, we need to calculate the sum of the hydrogen atoms from water and ammonia.
1. Calculate the number of hydrogen atoms in water:
- The formula for water is H₂O, indicating two hydrogen atoms (H).
- Since there are 3.50×10²⁵ water molecules, we multiply this number by 2 to get the total number of hydrogen atoms in water:
Total hydrogen atoms in water = 3.50×10²⁵ water molecules * 2 hydrogen atoms/molecule
2. Calculate the number of hydrogen atoms in ammonia:
- The formula for ammonia is NH₃, indicating three hydrogen atoms (H).
- Since there are 5.00×10²⁴ ammonia molecules, we multiply this number by 3 to get the total number of hydrogen atoms in ammonia:
Total hydrogen atoms in ammonia = 5.00×10²⁴ ammonia molecules * 3 hydrogen atoms/molecule
3. Add the number of hydrogen atoms from water and ammonia to find the total:
Total hydrogen atoms = Total hydrogen atoms in water + Total hydrogen atoms in ammonia
Now, let's calculate the total number of hydrogen atoms in the solution.
