Answer:
I don't think (NH4)PMo12O40 is written properly, but if it is, there are 4 moles of hydrogen atoms for every 1 mole of (NH4)PMo12O40
Explanation:
1 mole of (NH4)PMo12O40 has 6.02x10^23 molecules of (NH4)PMo12O40. Each molecule of (NH4)PMo12O40 has 4 hydrogen atoms. If the molecule is decomposed to just it's elements, there would be 4 moles of hydrogen atoms for every one mole of (NH4)PMo12O40.
The number of moles of hydrogen atoms in one mole of (NH₄)PMo₁₂O₄₀ is 4. Hence, option A is correct.
What are moles?
Moles can be given as the mass of the compound to the molar mass.
Moles = Mass/Molar mass
The subscript to the H in the formula describes the number of hydrogen atom in a molecule.
Thus, 1 molecule of (NH₄)PMo₁₂O₄₀ contains 4 atoms of hydrogen.
1 mole = 6.023*10²³ molecules
1 molecule (NH₄)PMo₁₂O₄₀ = 4 hydrogen atoms
1 mole (NH₄)PMo₁₂O₄₀ = 6.023*10²³ * 4 hydrogen atoms
1 mole (NH₄)PMo₁₂O₄₀ = 4 moles of hydrogen atoms
Thus, the moles of hydrogen atoms present in 1 mole of (NH₄)PMo₁₂O₄₀ is 4. Hence option A is correct.
