A sample of ammonium phosphate,

{\left( {N{H_4}} \right)_3}P{O_4}

, contain 6 mole of hydrogen atoms. The number of moles of oxygen atoms in the sample is

View answer and explanation

Correct option: B

Option B (2) is correct because in one mole of ammonium phosphate, 12 moles of hydrogen atoms correspond to 4 moles of oxygen atoms, thus 6 moles of hydrogen correspond to 2 moles of oxygen.
