Answer:
4. 15
Explanation:
The given formula is:- [tex](NH_4)_2SO_4[/tex]
1 mole of the salt contains 2 moles of nitrogen atom, 8 moles of hydrogen, 1 mole of sulfur and 4 moles of oxygen atom as can be seen from the formula.
Thus,
1 mole of salt contains total of 15 moles of the atoms which constitute the salt.
Hence, 4. is the answer.
15 moles of atoms are present in the compound [tex]\rm (NH_{4})_{2}SO_{4}[/tex].
The number of the particles present in an Avogadro number is called the moles. It can be of molecules, atoms, or ions. It is represented as mol.
How to calculate the moles?
The formula of the compound is [tex]\rm (NH_{4})_{2}SO_{4}[/tex].
From the formula of the compound, it can be deduced that 1 mole of salt contains:
- Moles of nitrogen atom = 2
- Moles of hydrogen atom = 8
- Moles of sulfur atom = 1
- Moles of oxygen atom = 4
The total number of moles:
[tex]2 + 8 + 1 + 4 = 15[/tex]
Therefore, option 4. 15 moles of atoms constitutes 1 mole of the salt.
