A solution of ammonia and water contains 1.60×1025 water molecules and 8.50×1024 ammonia molecules. How many total hydrogen atoms are in this solution?

H atoms in water = 2*1.60E25

H atoms in NH3 = 3*8.50E24
Total = ?

5.15

To find the total number of hydrogen atoms in the solution, we need to consider both water (H2O) and ammonia (NH3).

First, let's calculate the number of hydrogen atoms from water molecules:
1 water molecule (H2O) contains 2 hydrogen atoms.

To convert the number of water molecules (1.60×10^25) to the number of hydrogen atoms, we need to multiply it by 2:
Number of hydrogen atoms from water = 1.60×10^25 water molecules × 2 hydrogen atoms/molecule

Next, let's calculate the number of hydrogen atoms from ammonia molecules:
1 ammonia molecule (NH3) contains 3 hydrogen atoms.

To convert the number of ammonia molecules (8.50×10^24) to the number of hydrogen atoms, we need to multiply it by 3:
Number of hydrogen atoms from ammonia = 8.50×10^24 ammonia molecules × 3 hydrogen atoms/molecule

Finally, to find the total number of hydrogen atoms, we add the number of hydrogen atoms from water to the number of hydrogen atoms from ammonia:
Total number of hydrogen atoms = Number of hydrogen atoms from water + Number of hydrogen atoms from ammonia

Let's calculate it:
Number of hydrogen atoms from water = (1.60×10^25) × 2 = 3.20×10^25 hydrogen atoms
Number of hydrogen atoms from ammonia = (8.50×10^24) × 3 = 2.55×10^25 hydrogen atoms

Total number of hydrogen atoms = (3.20×10^25) + (2.55×10^25) = 5.75×10^25 hydrogen atoms

Therefore, there are approximately 5.75×10^25 hydrogen atoms in this solution.
