Question

One mole of (nh4)2hpo4 contains how many moles of hydrogen atoms?

Answer 1

9 Moles of Hydrogen atoms

Step-by-step explanation:

In order to answer this question, we can use the analogy of a motor car.

One car contains 1 steering wheel, 2 headlights and 4 tyres.

Similarly, 1 mole of
`(NH_(4) )_(2) HPO_(4)` contains 9 moles of hydrogen atoms. One mole points to 6.02
`X 10^(23)` number of particles.

WORKING:

In
`(NH_(4) )_(2) HPO_(4)`, there are 4x2 = 8 Hydrogen atoms in
`(NH_(4) )_(2)` and 1 Hydrogen atom in
`HPO_(4)`. Therefore, there are 8+1= 9 moles of Hydrogen atoms.

Answer 2

2 NH4+ contribute 8 mols of H
There is 1 more mol of H infront of the PO4+3

9 mols H <<<<<===== answer.
