How many H are there in 3NH4OH? 4 will be in the down.
The correct answer and explanation is:
The chemical formula you provided is 3NH₄OH, which refers to three molecules of ammonium hydroxide. To find the number of hydrogen atoms in this compound, let’s break it down:
- NH₄OH is ammonium hydroxide. The NH₄ part represents the ammonium ion (NH₄⁺), and the OH part represents the hydroxide ion (OH⁻).
- In the NH₄⁺ ion, there are 4 hydrogen atoms. Each hydrogen atom is bonded to the nitrogen atom.
- The OH part contains 1 hydrogen atom.
So, in one molecule of NH₄OH, there are a total of 4 (from NH₄) + 1 (from OH) = 5 hydrogen atoms.
Now, since you have 3NH₄OH, the total number of hydrogen atoms is:
- 5 hydrogen atoms per molecule × 3 molecules = 15 hydrogen atoms.
Thus, in 3NH₄OH, there are 15 hydrogen atoms in total.
This calculation illustrates how to count the number of hydrogen atoms in a compound by analyzing its molecular formula. Each element’s subscript indicates how many atoms of that element are present in the molecule. When there is a coefficient (like 3 in front of the formula), it multiplies the number of atoms in each part of the molecule. In this case, multiplying by 3 increases the total number of hydrogen atoms from 5 (in one molecule) to 15 (in three molecules).
