A sample of ammonium phosphate contains 3.18 moles of hydrogen atom. t

1.	A sample of ammonium phosphate contains 3.18 moles of hydrogen atom. the number of moles of oxygen atom in the sample is ???
Answer» $\Huge\blue{\mathfrak{\underline{\underline{answer}}}}$ $\large\red{\textbf{<klux>1</klux>.06 <klux>MOLES</klux>}}$ $\Huge\blue{\mathfrak{\underline{\underline{Solution}}}}$ → 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.

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

$\large\red{\textbf{<klux>1</klux>.06 <klux>MOLES</klux>}}$

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

→ 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.
