Question

If a sample of ammonium phosphate contain 3.18 moles of hydrogen atoms then what is the number of moles of oxygen atoms in the sample

Answer 1

HELLO THERE!

Given, a sample of Ammonium Phosphate contains 3.18 moles of hydrogen atoms.

Formula: (NH₄)₃PO₄

Moles of H atoms = 12

Moles of O atoms = 4

Now, 12 moles of H atoms mean 4 moles of O atoms.

So, 3.18 moles of H atoms mean:

$\frac{4}{12}\times3.18 = 1.06 moles$

So, there are 1.06 moles of Oxygen atoms in the given sample of ammonium phosphate.

HOPE MY ANSWER IS SATISFACTORY...

Thanks!

$\large\red{\textbf{1.06 moles}}$

$\Huge\blue{\mathfrak{\underline{\underline{Solution}}}}$

→ 1 mole of (NH4)3PO4 will contain 12 mole H- atom

→ So, 3.18 mole of H-atom will be present in

→ 1/12 × 3.18 moles of (NH4)3PO4

= 0.265 moles of (NH4)3PO4

→ 1 mole of (NH4)3PO4 contains 4 moles of H-atom.

→ So, 0.265 (NH4)3PO4 will contain

→ 4×0.265 = 1.06 moles of oxygen atoms.
