A solution of ammonia and water contains 2.90×1025 water molecules and 9.00×1024 ammonia molecules. How many total hydrogen atoms are in this solution?
any help would be great.
There are 2*2.9-E25 H atoms in the H2O.
There are 3*9.00E24 H atoms in the NH3.
Total = the sume of the two.
To find the total number of hydrogen atoms in the solution, you need to consider the number of hydrogen atoms in the water molecules and ammonia molecules separately.
Let's start with the water molecules. Water, or H2O, contains two hydrogen atoms per molecule. So, to find the number of hydrogen atoms in the water molecules, you multiply the number of water molecules by 2 (since there are two hydrogen atoms per molecule).
Number of hydrogen atoms in water = 2.90×10^25 water molecules * 2 hydrogen atoms per water molecule = 5.80×10^25 hydrogen atoms in the water
Next, let's consider the ammonia molecules. Ammonia, or NH3, contains three hydrogen atoms per molecule. So, to find the number of hydrogen atoms in the ammonia molecules, you multiply the number of ammonia molecules by 3 (since there are three hydrogen atoms per molecule).
Number of hydrogen atoms in ammonia = 9.00×10^24 ammonia molecules * 3 hydrogen atoms per ammonia molecule = 2.70×10^25 hydrogen atoms in the ammonia
Now, to find the total number of hydrogen atoms in the solution, you simply add the number of hydrogen atoms in the water and ammonia.
Total number of hydrogen atoms = 5.80×10^25 hydrogen atoms in the water + 2.70×10^25 hydrogen atoms in the ammonia
= 8.50×10^25 hydrogen atoms in the solution
Therefore, there are 8.50×10^25 hydrogen atoms in the solution of ammonia and water.
To determine the total number of hydrogen atoms in the solution, we need to consider the number of hydrogen atoms present in both water (H2O) and ammonia (NH3).
1. Water (H2O) contains 2 hydrogen atoms.
2. Ammonia (NH3) contains 3 hydrogen atoms.
Let's calculate the total number of hydrogen atoms in the solution:
For water:
Number of water molecules = 2.90×10^25
Number of hydrogen atoms in 1 water molecule = 2
Total number of hydrogen atoms from water = Number of water molecules × Number of hydrogen atoms in 1 water molecule
Total number of hydrogen atoms from water = (2.90×10^25) × 2
For ammonia:
Number of ammonia molecules = 9.00×10^24
Number of hydrogen atoms in 1 ammonia molecule = 3
Total number of hydrogen atoms from ammonia = Number of ammonia molecules × Number of hydrogen atoms in 1 ammonia molecule
Total number of hydrogen atoms from ammonia = (9.00×10^24) × 3
Finally, to calculate the total number of hydrogen atoms in the solution, we add up the number of hydrogen atoms from water and ammonia:
Total number of hydrogen atoms = Total number of hydrogen atoms from water + Total number of hydrogen atoms from ammonia
I hope this helps!
