To determine the number of moles of N and H atoms in 1 mole of (NH4)2SO4, we need to examine the chemical formula and count the respective atoms.
The formula (NH4)2SO4 represents the compound ammonium sulfate. Let's break it down:
(NH4)2: This indicates that there are two ammonium ions (NH4+) in the compound. Each ammonium ion consists of one nitrogen atom (N) bonded to four hydrogen atoms (H).
SO4: This represents the sulfate ion (SO4^2-), which consists of one sulfur atom (S) bonded to four oxygen atoms (O).
Now, let's count the number of N and H atoms:
- In two ammonium ions [(NH4)2], there are 2 nitrogen atoms (N) and 8 hydrogen atoms (H) in total.
Therefore, in 1 mole of (NH4)2SO4, there are 2 moles of nitrogen atoms (N) and 8 moles of hydrogen atoms (H).
