Question

A sample of ammonium phosphate, ( NH 4)3 PO 4, 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

If 3.18 mol of hydrogen atom are there, then number of moles of oxygen atoms =(3.18/2) mol =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:

$0.265$

$0.795$

$1.06$

$3.18$

If $3.18 m o l$ of hydrogen atom are there, then number of moles of oxygen atoms

$= \frac{3.18}{2} m o l = 1.06 m o l$
