Question

A sample Of ammonium phosphate, (NH 4 P04, contains 6 moles of hydrogen atoms. The
number of moles Of oxygen atoms in the sample is:

Answer 1

No. of H-atoms =12

No. of O-atoms =4

No. of moles of hydrogen atoms = 6

No. of moles of oxygen atoms = n_O

∴ so, ratio of no. of atoms =  ratio of no. of moles

$\frac{12}{4}$ = $\frac{6}{n_o}$

n_{O =} $\frac{24}{12}$

n_O = 2
