Question

A sample amount of ammonium phosphate contains 3.18 moles of hydrogen atoms.the number of. moles of oxygen atom in the sample is

Answer 1

There is one moles of oxygen atoms per mole of water (given by the formula H2O).

There are Avogadro’s number of particles in every mole of anything (6.02 x 10^23), so there are 0.16 x 6.02 x 10^23 individual oxygen atoms in 0.16 moles of water, or 9.64 x 10^22.

Answer 2

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

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

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

→ 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.
