Question

A sample of ammonium phosphate, (NH4)3PO4, contains 3.18 moles of hydrogen atoms. The number of moles of oxygen atoms in the sample is (A) 0.265 (B) 0.795 (C) 1.06 (D) 3.18

Tardigrade Admin · Accepted Answer

In one mole of (NH4)3PO4, 12 moles of hydrogen atoms 4 moles of oxygen atoms, 3 moles of nitrogen atoms and 1 mole of phosphorus atoms are present If 3.18 mole of hydrogen atom are there, number of moles of oxygen atoms =(3.18/3) mL =1.06 mol

Q. A sample of ammonium phosphate, $(N H_{4}) 3 P O_{4}$ , contains 3.18 moles of hydrogen atoms. The number of moles of oxygen atoms in the sample is

0.265

0.795

1.06

3.18

In one mole of $(N H_{4})_{3} P O_{4}$ , $12$ moles of hydrogen atoms $4$ moles of oxygen atoms, $3$ moles of nitrogen atoms and $1$ mole of phosphorus atoms are present
If $3.18$ mole of hydrogen atom are there, number of moles of oxygen atoms $= \frac{3.18}{3} m L$
$= 1.06$ mol
