Short Answer

Problem:

A sample of ammonium phosphate (NH4)3PO4 contains 3.18 moles of hydrogen atoms. Calculate the number of moles of oxygen atoms in the sample?


Solution:

In (NH4)3PO4, moles of 'H' are present with 4 moles of oxygen atom.

So, 3.18 moles of 'H' are present with = 4 over 12 cross times 3.18

= 1.06 moles of oxygen atom
