A solution of ammonia and water contains 2.70×1025 water molecules and 7.60×1024 ammonia molecules. How many total hydrogen atoms are in this solution?

H atoms in water = 2.70E25 x (2 atoms H/1 molecule H2O)?

H atoms in NH3 = 7.60E24 x (3 atoms H/1 molecule NH3) = ?

The sum will give you the total numbr of H atoms.

28.2

To determine the total number of hydrogen atoms in the solution, we need to consider the number of hydrogen atoms in water and ammonia separately.

1. Water (H2O):
In each water molecule, there are 2 hydrogen atoms.
Number of water molecules = 2.70 × 10^25
Total number of hydrogen atoms in water = 2 × number of water molecules
= 2 × 2.70 × 10^25

2. Ammonia (NH3):
In each ammonia molecule, there is 1 hydrogen atom.
Number of ammonia molecules = 7.60 × 10^24
Total number of hydrogen atoms in ammonia = 1 × number of ammonia molecules
= 1 × 7.60 × 10^24

Now we can calculate the total number of hydrogen atoms in the solution by adding the number of hydrogen atoms in water and ammonia:

Total number of hydrogen atoms = Total hydrogen atoms in water + Total hydrogen atoms in ammonia

Total number of hydrogen atoms = 2 × 2.70 × 10^25 + 1 × 7.60 × 10^24

Please calculate the expression to get the final answer.

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, and then add them together.

Step 1: Calculate the number of hydrogen atoms in water:
According to the chemical formula H2O, there are 2 hydrogen atoms in each water molecule.
Number of water molecules = 2.70×10^25
Number of hydrogen atoms in water = 2 × (2.70×10^25) = 5.40×10^25

Step 2: Calculate the number of hydrogen atoms in ammonia:
According to the chemical formula NH3, there is 1 hydrogen atom in each ammonia molecule.
Number of ammonia molecules = 7.60×10^24
Number of hydrogen atoms in ammonia = 1 × (7.60×10^24) = 7.60×10^24

Step 3: Add the number of hydrogen atoms in water and ammonia together:
Total number of hydrogen atoms = Number of hydrogen atoms in water + Number of hydrogen atoms in ammonia
Total number of hydrogen atoms = 5.40×10^25 + 7.60×10^24
Total number of hydrogen atoms = 6.16×10^25

Therefore, there are 6.16×10^25 hydrogen atoms in this solution.
