Answer:
6.40x10²⁵ hydrogen atoms
Explanation:
The solution contains:
- 1.80x10²⁵ water molecules (H₂O)
- 7.00x10²⁴ ammonia molecules (NH₄)
We need to calculate the total of hydrogen atoms (H) in the solution.
- Each water molecule (H₂O) has 2 hydrogen atoms
- Each ammonia molecule (NH₄) has 4 hydrogen atoms
Lets now calculate the number of hydrogen atoms in the solution:
total H atoms = (H atoms in water molecules) + (H atoms in ammonia molecules)
total H atoms = (2 x 1.80x10²⁵) + (4 x 7.00x10²⁴) =
total H atoms = 3.60x10²⁵ + 2.80x10²⁵ = 6.40x10²⁵
